I think it's still a valid video to show the basis to a middle school biology class. In fact, too many jargons and complicated steps can easily turn students off.
Clearly the reason this is so simple is because it is designed for people who are new to the concept of DNA replication. I'm in year 10 and I found it quite useful because we're not focusing on details yet. If you guys need something precise with more information, click on a different video. So immature!
This video is perfect when students don't need to know the names of the enzymes or the ENTIRE process of replication. Sometimes those details just aren't necessary and showing a video with info they don't need just confuses them.
I watched this in Biology Honors- I am in seventh grade, and I can only assume that this video was created for use by a lower grade than those that are seeking the information complained about in the comments below. ^_^
Recent studies show that positive emotion/thought such as love, joy, greatfulness and etc. effects human DNA by making the strands longer and more perceptive (meaning uncoding the hidden talents such as ESP, precognition, clairvoyance and others), when negative emotion such as fear, anger, despair and etc. makes DNA shrink, therefore limiting human perception a great deal. One has to establish an ongoing positive thought in order for these change to occur.
@RUSSKAYAG Please... if you're going to make claims that contradict common knowledge on the subject at hand, provide at least a shred of evidence. No one will take that kind of claim seriously unless you reveal the source.
This is kind of bogus. It refers to "an enzyme" and then "another enzyme." It also implicates that the two strands are simultaneously synthesized on both sides of the replication fork and overlooks the concepts of leading and lagging strands, the need for Okazaki fragments, the role of helicase and topoisomerase, and the role of ligase in sealing the new fragmented strand.
@insane247 enzyme that 'unzips' them is call helicase and the enzyme that joins the nucleotides are called polymerase.. but you probably knew that anyway
It gives one part of the missing information in each dna replication video in youtube. That is this video shows that the polymerases needs rna nucleotides scattered around to replicate the dna. The other videos just like magic, dna forms out of nowhere with nothing but polymerases and binding proteins.
It's hilarious to see people spamming the video just because it's not informative and accurate enough. LOLS just move on to the next vid and DEAL WITH IT. -.-||
this was a bit vague but it might do me some good for my honors biology class. people if you don't wanna learn it, keep your' moronic comments to your'self, and andywedga, it isn't something to be proud of to say you are 38 and you still say idiotic profanitys to ppl. it'd do you good to grow up. ^_^
Not everyone is in an advanced biology class. I find this a good introduction to a high school class before getting into the terminology. @ DollProductions. True, Franklin first took xray pics of the structure and Crick pieced it together while on an acid trip. LSD was frequently used by scientists to "expand their creativity". And steal other people's hard work. Franklin died before her achievement was recognized while W & C won the Nobel Prize.
@sporks4all simplistic to say she was robbed. she was the author of her own misfortune. her antisocial attitude did her in. knowledge needs light. you don't lock a photo like that in a desk.
@DollProductions1 untrue. the photo did not map dna. a lot of work went into understanding what could cause an x ray to look like that... would she have come up with it, the photo locked in her desk? no one knows but the photo itself is not the double helix discovery.
I like it, i dont need to go to in depth for it and the other videos have too much info and i get confused.. Good for some bad for others all depends what ur lookin for.
@marinaasouza I think you forgot to thank the author of this video before you express your disappointment. I'm just thankful that someone exerted an effort to post video like this. Somebody needs to proofread this person's DNA please.
@Fairieswell What's the point of making a video that is innacurate? If I'd make a video showing how bird fly because they have a jet engine in their ass, would you thank me for my effort? No. You'd say I'm damn stupid.
This video is all wrong. The DNA isn't replicated in regions simultaneously, the Polimerase 3 is continuosly bonding 1 strand, while the other strand must be replicated from toe to head, so to speak. There's a lot more going on.
No, I completely agree with this guy. He is 100% right! This shouldn't be an essential part of schooling, it should only be taken by students that WANT to obtain a higher education. Besides, it's an easier way of narrowing down who is going to bag my groceries in the future after college :)
you shut the fuck up biology is your life.dna actually replicates by the transcription process. suck dicks if you hate biology. FUCKERS im 38 years old and i know biology. so suck on big elephants dicks.
38 and still telling people to suck elephant dicks, your life must be fascinating, bet your kids are proud? oh wait, you dont have kids because for kids to be created you need a women and lets face it.. telling people to suck elephant dick at 38 just turns women on doesnt it. Congrats.
Wow. Awesome. Whoever hates biology needs to think: Without these tiny components they would be NOTHING. Of coarse, the enzymes do have names but this is good enough.
this isn't specific the enzyme is called DNA Helicase which splits the DNA first round then DNA Ligase joins them up or Polymerase. Poor Video Poor Video
this isn't specific the enzyme is called DNA Helicase which splits the DNA first round then DNA Ligase joins them up or Polymerase. Poor Video Poor Video
Actually DNA polymerase 3 and DNA polymerase 1 act as quality control checkers by proofreading the newly synthesized strand, cutting out any incorrectly paired nucleotides.
DNA polymerase can only work in the 5'-3' direction. In the video, those proteins attaching the nucleotides should be moving in the same direction. The lagging strand (the two strands look to be leading strands in the video) does this by using a region of RNA primer that DNA primase places down. All this occurs because of the bioenergetics of DNA replication...5'-3' is a favorable reaction (3'-5' is not), and DNA replication can only start if it has an RNA primer.
most humans don't understand all this.. this shit is way to complex to be random... LIFE must be written.. by God.. the Source.. The Great Spirit.. whatever you want to call it..
Physicist around the world are so mad that all of their math equations about the universe always lead back to a creator, no matter what the figure out it all goes back to creation, the best physicists in the world have admitted this, but, they keep trying to prove there is no creator.
The latest report was a few weeks ago from Oxford University, they say that their math equations no matter what they do not make sense, unless there was a creator. I'll send you some documentaries, the "question" is thrown back and forth.
Yep...I agree. This video is most useful to the wall street executive who wants to know some tiny information about Biology. Too simple even for kids.
To me , even a single plant , flower or a tree is a miracle , and a mystery . How can we explain that all atoms , molecules , cells , can self-organize and grow to make a living organism with functional tissues and organs ? it's magic !
What, the nucleotides are just randomly free? I thought they detach from datp, dgtp, dttp, and dctp and attach to the previous nucleotide in the strand by being powered by the high energy phosphate bonds.
WOW This is sooo wrong...wheres the polymerase...the video shows two strands being replicated by two different enzymes...in fact one polymerase replicates both DNA strands simultaneously...this video is incorrect
You're absolutely correct. That's also the reason why the lagging strand has to make a 'twist' to be oriented correctly when it goes into the polymerase. This is an oversimplification.
Remember, we must never assume DNA replication was designed! Remember, when your Biology teacher tells you this evolved randomly, bow down before him, and suck on his big toe!
This video is a good introduction to DNA replication for middle school or high school students. For a solid understanding, it *must* be followed up with another video that shows the difference between the leading and lagging strands of DNA, directionality, okazaki fragments etc.
