We had to watch this in Bio today. .__. Am I the only one who finds that wiggly thing creepy? And is considered that I don't know what that wiggly thing is?
@tteu123 I'm in ib hl right now and I see where you're coming from. So much goddamn material and I'm stuck with a teacher who has barely taught us a single biological process. I have my midterm tomorrow. CRAM TIME.
@Transfusions Everything is highly concentrated in the cell, which is a very very tiny place, and all moves very fast, (this is called brownian motion). Eventually the "right substances" get the the "right location"
@N0M4D88 Interesting. so it's more of probability theory by brownian motion than intermolecular force or something like that? I shouldn't have skipped biology class when I was in high school.
@Transfusions Not sure i got what you mean by that. Brownian motion is the force that will bring the tRNAs to the ribosome, but when the right tRNA "plugs" in the right codon of the mRNA in the ribosome, intermolecular forces intervene (small changes of conformation (shape) of the ribosome, which stabilizes it). Energy is released from this compatible interaction and it allows the aminoacid to link with the peptide in formation, the tRNA to be released and the ribosome to move up one codon.
I dont get this part, each transfer molecule has a unique three letter code, there are 20 amino acids each with its own three letter code. which is fine, Now the ribosome matches the three letter code on the RNA with the correct transfer molecule and hence amino acid to build the protein, which is fine, but who brings them in order? what if the correct transfer molecule doesnt come along? Will the machine(ribosome) just wait? Its just a dumb chemical, how does it have intelligence like that?
@ashwinbhat123 The transfer molecules, called tRNAs, don't really get "brought in order". They basically float around and get to the ribosome thanks to brownian movements (everything moves really fast at the molecular level) so eventually the right tRNA will find its match. If it doesn't "fit" the codon (The three letter nucleotide code in the mRNA) the link won't be stable and it'll be replaced by the right tRNA eventually. Look it up in wikipedia, it's rather trustworthy for scientific topics.
I had to watch this video three times before I finally understood what was being taught. I haven't had biology since high school and even then I didn't understand. I'm one of the stupid ones! Thanks for posting!
This is the most crazy compli-fuckin-cated thing ever! If your mind did not have a mini stroke when you watched this you better open your eyes wider and rewind. If you proposed this idea before modern science had studied it you would have been burned at the stake immediately. How does this transcription mechanism not have some sort of conscious entity driving it like a tractor? We live in the craziest place and we all just sit around and reject the enormity and profound mystery. Let's wake UP!!
@jsummonsm1 The "conscious entity" does not exist on this level of nature. It's a mixture of the properties of atoms (electonegativity etc.) and distribution / concentration of them.
@Zimminimal You say this as if you KNOW. I studied for many years in chemistry and molecular biology probably like you and in no way can you sum up these series of movements by some quantum mechanical dogma that was vomited out by your professor. Do you seriously think we have any grasp of this shit? Our text books say "this is how it works" but what they really mean to say is "we have spent a fuckton of time and money studying this, but our little monkey brains can't quite get there yet"

So in real life its not like the transfer molecules "know" that its their turn to go into the ribosome (which is what it seems like in the video), but the process of translation won´t continue until the right transfer molecule gets inside to match the code? I´m wondering if my guess is correct...
@HunterLovell Yes, it is exactly as you say. The tRNAs (transfer molecules) goes into ribosome randomly, and the process goes on when the right tRNA is found (the right one means that it match the mRNA template [the yellow chain]).
the sound affects and realistic quality of this video make it pretty epic. i'd sit and watch this all day rather than sit through a 2 hour lecture and 3 hour lab.
So amazing. I feel so lucky to be living in an age of technology and information. That we can know so much about our world and ourselves. I wish more funding would go into the sciences, instead we waste time fighting in wars and giving millionaires more money to buy more yachts. Every student in college wants to go into advertising or something as equally meaningless. I love science and I wish I could comprehend and grasp all of the sciences. I'm trying my best to learn more every day.
I have a biology final tomorrow, and for my essay question i have to explain how you make protein from DNA - but it focuses very heavily on translation and transcription.
I still don't entirely understand it, so if someone could please please explain the whole process to me in layman's terms that would be sooo much appreciated!
Such a cracking video I class it as a form of revision for my A2 bio exam next week- who said revision wasn't fun?!... definitely should be more videos like this.
1) Why doesn't this talk about introns and exons? ):
2) Where does that one amino acid attached on the tRNA come from? What I mean is, does a tRNA exist with an amino acid naturally, even before translation process, or is the amino acid made during the translation process?
3) If the tRNA exists beforehand with an amino acid, how is that amino acid created?
Please answer my exams are next week and this is a bit unclear to me.
1) This video avoids talking about introns and exons for simplicity. Best to consult a book for clarification on that.
2) The amino acid is added to the tRNA before trannslation begins - there's a whole process where each tRNA gets its own cognate amino acid added to it.
3) Amino acids are basic building blocks that usually already exist ... proteins are broken down into amino acids and these are re-used by being attached to tRNAs and getting added to new proteins.
@msc0328 At 1:38 the video says that "The letter 'T' is replaced with a closely related nucleic acid known as 'U'." Shouldn't it be a nitrogenous base?
@msc0328 This video avoids talking about a lot of things. I don't think it would complicate matters to mention what exactly the "blue molecule" or the clump of stuff at the beginning of the video would complicate the material at all. In fact, it would help to know the names!
Amazing how complex this process is, and even more amazing how this is the very basics of the innumerable interactions between the billions of cells in our body.
wow .. cool i got a little bit of understanding here , but great and detailed information .. thank you for these kind of videos , what could i possibly done without it .

@Carlitosway86 "transcription factors" are molecules that bind to DNA and either promote or inhibit the recruitment of RNA Polymerase II to that area so that transcription can or cannot occur.
@msc0328 ok I dug around and found this " triggered when proteins called transcription factors bind to the promoter region of the gene" so in essence proteins, thanks for your explanation as well. Also if anyone is interested, recently this news was leaked regarding transcription (2nd news bit down) Hopefully we get to see this real-time footage very soon.

Just type in "SCIENTISTS OBSERVE SINGLE GENE ACTIVITY IN LIVING CELLS" in any search engine.
@msc0328 Ok so these transcription factors are essentially just proteins, thanks. I found some very interesting news regarding real time footage of transcription in a living cell, hopefully it gets shared with the public in the near future. :) It's very recent researched (published on Apr. 22 of this year) just search for "SCIENTISTS OBSERVE SINGLE GENE ACTIVITY IN LIVING CELLS" and you'll pull it up.
@Lightscribe225 Its all infront of your eyes mate.. i have been studying sciences for over 4 years and its just mind blowing and just look at all these videos of how everything is working at the same time and each function has a mind of its own.. immposible for it to all be by chance. There is so many more reasons.
@Treckorz Well when you consider that the cell has had billions of years of screw ups that died off, it doesn't seem so mind boggling. Besides evolution is happening right now with those steaks everyone eats.
@Lightscribe225 Thats a theory with no proof. They back the suffesticated cell the with "theory" "proof" that it happened because of so many screw ups, but there is no hard evidence for it. Trust me my friend im not little child im going onto doing my phd in pharmacy, and i tell you right now if all the pieces of the puzzle fit together i would of been a big believer of evolution, but they dont! I am very open minded and do my research and hardcore thinking. :) peace.
@Treckorz Of course it's theory. Nearly everything in science is theory. But it is accepted theory until something with more solid results knocks it off the pedestal. And the proof that it works is the fact it exists and the ones that didn't are now fossils buried in rock.
If it ain't evolution that did this then what? And I'm also majoring in biology, going into radiology, so let's try and keep that out of the mix.
@Lightscribe225 I see where yo uare commig from, Il tell you something; i dont think that evolution did not take part at all, i think it did contribute to life in a way however i totaly disagree with the big bang theory and how the earth was created out of space and slowley life was formed etc. And that apes are a common ancestor i still havnt found hard evidence. There are people i kno who believe in evolution but at the same time believe in the 1 created of the universe a religion.
Great video, you can read and read and read the chapter on DNA, but when you see it in action like this, it really comes together. Thank you for posting this !!!! Was a great help. :)
So Atheist people your telling me that all of this just happens....there is no power up above that controlls this??......get outta here.......This is all God's creation
@Stanley81 you are ignorant beyond words, you do realize that you sound like a moron, if you ever went to school or studied at a higher level you would understand where the energy comes from, you're little mind is too ignorant to even ask that question, you just assume and think that god does anything you don't understand, go get an education then you can comment appropriately
This video just drives me crazy. It's like that voice is saying "See? We just explained the whole thing to you. No more questions please.......run along now."
seriously you guys this video deserves an A+. cause of this i actually get it now. it took my teacher and classmates to explain but nobody did it as effective nor efficient as this did. PLease you guys learn of this video. educate yourselves and others ;]
how come the blue molecule,during transcription,rails through the DNA strand like that? Where does it get the energy from?It's a molecule...what are its components???
@Uchchash That molecule is RNA polymerase II - look it up on wikipedia because that question is a bit too big to answer here. It's energy comes from ATP (like many other enzymes in the cell). This particular molecule is *very* quickly hydrogen bonding to particular nucleotides and matching it up with their complementary letter to synthesize a string of RNA.
@TheSvenw007 I actually don't know the answer to that question, or an easy place to get the answer. There biochemical reactions are usually studied in isolation, and then the actual en vivo rates are estimated from factoring in real life variables. Why do you want to know how many nucleotides are incorporated per second?
I dunno how many nucleotides are copied for transcription per second but during translation, 2 amino acids are added to the chain per second in eucaryotes and 20 per second in procaryotes

@msc0328 ok I dug around and found this " triggered when proteins called transcription factors bind to the promoter region of the gene" so in essence proteins, thanks for your explanation as well. Also if anyone is interested, recently this news was leaked regarding transcription (2nd news bit down) Hopefully we get to see this real-time footage very soon.

@msc0328 Ok so these transcription factors are essentially just proteins, thanks. I found some very interesting news regarding real time footage of transcription in a living cell, hopefully it gets shared with the public in the near future. :) It's very recent researched (published on Apr. 22 of this year) just search for "SCIENTISTS OBSERVE SINGLE GENE ACTIVITY IN LIVING CELLS" and you'll pull it up.

in translation do the tRNA's always possess the anti-codon that pairs with the codon or are there errors?

Lightscribe225 9 months ago
@Lightscribe225 Its all infront of your eyes mate.. i have been studying sciences for over 4 years and its just mind blowing and just look at all these videos of how everything is working at the same time and each function has a mind of its own.. immposible for it to all be by chance. There is so many more reasons.
Treckorz 9 months ago
@Treckorz Well when you consider that the cell has had billions of years of screw ups that died off, it doesn't seem so mind boggling. Besides evolution is happening right now with those steaks everyone eats.
Lightscribe225 9 months ago
@Lightscribe225 Thats a theory with no proof. They back the suffesticated cell the with "theory" "proof" that it happened because of so many screw ups, but there is no hard evidence for it. Trust me my friend im not little child im going onto doing my phd in pharmacy, and i tell you right now if all the pieces of the puzzle fit together i would of been a big believer of evolution, but they dont! I am very open minded and do my research and hardcore thinking. :) peace.
Treckorz 9 months ago
@Treckorz Of course it's theory. Nearly everything in science is theory. But it is accepted theory until something with more solid results knocks it off the pedestal. And the proof that it works is the fact it exists and the ones that didn't are now fossils buried in rock.
If it ain't evolution that did this then what? And I'm also majoring in biology, going into radiology, so let's try and keep that out of the mix.
Lightscribe225 9 months ago
@Lightscribe225 I see where yo uare commig from, Il tell you something; i dont think that evolution did not take part at all, i think it did contribute to life in a way however i totaly disagree with the big bang theory and how the earth was created out of space and slowley life was formed etc. And that apes are a common ancestor i still havnt found hard evidence. There are people i kno who believe in evolution but at the same time believe in the 1 created of the universe a religion.

@Stanley81 you are ignorant beyond words, you do realize that you sound like a moron, if you ever went to school or studied at a higher level you would understand where the energy comes from, you're little mind is too ignorant to even ask that question, you just assume and think that god does anything you don't understand, go get an education then you can comment appropriately

by da way,how does the mRNA strand travels to the ribosomes on rough ER?And how the tRNA strands get attracted to the ribosomes??
Uchchash 10 months ago
how come the blue molecule,during transcription,rails through the DNA strand like that? Where does it get the energy from?It's a molecule...what are its components???
Uchchash 10 months ago
@Uchchash That molecule is RNA polymerase II - look it up on wikipedia because that question is a bit too big to answer here. It's energy comes from ATP (like many other enzymes in the cell). This particular molecule is *very* quickly hydrogen bonding to particular nucleotides and matching it up with their complementary letter to synthesize a string of RNA.
msc0328 10 months ago 6
@Uchchash I believe the energy comes from the enzyme breaking that phosphodiester bond temporarily, but that could be incorrect

how many bases of the dna are copied via transscription a second (at the beginning of the vid)??
TheSvenw007 11 months ago 2
@TheSvenw007 I actually don't know the answer to that question, or an easy place to get the answer. There biochemical reactions are usually studied in isolation, and then the actual en vivo rates are estimated from factoring in real life variables. Why do you want to know how many nucleotides are incorporated per second?
msc0328 11 months ago
@msc0328 yes, that is what i mean
TheSvenw007 11 months ago
@TheSvenw007
I dunno how many nucleotides are copied for transcription per second but during translation, 2 amino acids are added to the chain per second in eucaryotes and 20 per second in procaryotes
