@aliwyatt407 Not because you are a brainless person who doesn't want to learn anything, means that you have to punish everyone else. He is helping everyone with his videos, and you tell him to stop? What a dumb ..... Lets just leave it like, dumb person ;)
@onefive10 I'm glad he repeats stuff because you have to hear something three times before it cemented into your brain, also teachers try to cram too much into a small amount of time so they try NOT to repeat themselves
@7RonaldoM Bio isn't a science that you "use." It is one that you understand. Biology is life, literally. So while you probably won't NEED to know this for the rest of your life it's one of the more useful subjects and can help you with other sciences since they overlap. And with your thinking we wouldn't need many subjects. Btw "fucking retardest shit".... really?
@7RonaldoM A lot of careers need you to be knowledgeable in biology, but you wouldn't know anything about that, now, would you, Mr. "Fucking Retardest Shit"?
@7RonaldoM Well if not in your career, then why do you feel the need to be a bigot on biology related videos? You can have your fun in quantum mechanics and we'll have ours in biology.
I've studied this two years ago in class and didn't understand the differences between chromosomes, chromatin and chromatids, I read 2 different bio books and still didn't understand... today I was trying to explain it to my sister and found your video, and in less than 20 min we learned it easily! Thank you!
I would also like to thank you for what you are doing Mr. Khan i would have zero chance of passing biology without your many videos. I wish u much more success in your mission and once again thank you
dude at the replication you can't switch side on the "letters" because then they will form another subjekt. just a small thing to think about. but beside from that i loved the video
He's generalizing religious people as non believers in these scientific ideals, which is complete and utter nonsense. I'm christian and i have to other explanation as to what goes on in our body's, so i accept the fact that this is fact. it's when we get onto the topic of evolution that we have something to rave about..
uh hey "idiot", yeah i'm christian too, and i actually do believe that this stuff goes on in your body..i dont think it says anywhere in the bible that it doesn't so yeah, but thanks for responding to something that was not for you..and btw either way disliking the video doesn't mean whoever did is even religious, it just means it's not a good video.thats why i responded to that person's comment.so mind your own business, yeah?
i completely agree with the difficult vocabulary dealing with chromosomes and chromatids. that's what has been confusing me in my genetics unit and you have just completely cleared it up. THANK YOU
omg...DNA replication and DNA transcription is different?! WOW. Why couldn't a textbook differentiate between the two?! I had no idea! My goodness. Such a simple idea is so unclear in a textbook. Thank you so much for posting this video. We college kids pay so much for a book that "has all the answers" and yet it makes simple concepts so complicated.
@Gzorz Hmm I wonder if I was...? Maybe, just maybe, I was dumb enough to say how I didn't know the difference between transcription and replication. Gosh that must be it.
...No Gzorz, I didn't. And now I know. You must be really smart...to look down on other people who know less about DNA transcription and DNA replication. Very very very very very very smart. Anyone else agree?
Gee I wonder why you're even watching this video. You're much much much much too smart. Go to Cornell.
I came here to disambiguate chromosome, chromatid and chromatin. I got exactly what I wanted. Thumbed up, favourited and subscribed - Thank you, I will be coming back to your channel for more subject, you made a damn god first impression

Thank you so much for clearing all of this up for me. i have a test coming up & all of this just wasn't making sense to me. Absolutely amazing at how your video makes it all so understandable & easy to grasp. THANK YOU, THANK YOU, THANK YOU!!!!!!
LOL... I am just amazed. Everybody comes and says that this online teachers (and yes they are teachers and not tutors, which a politically deceptive word meant to create unnecessary separation) that teach better than their own teachers at school, yet they are not ready to do something about it. Support these online teachers to get their own place (or online schools) and go to their schools. All these talk and no action.
how is it that your better than my bio professors? i guess its the chromo color in the explanation. and an actual explanation that doesnt disappear of the overhead in 5 sec. moving on to the next... i have so many feelings at this moment.
I was looking for Chromosome and Chromatid and CHromatin, not DNA replication!!! i was looking for definitions, what they do, what role they play, etc. Not amino acids and the bases of DNA.
@claudialovin It's just a misprint. Some people spell it chromosone, but that's really wrong. I think so at least, I have never read an article where it has turned out not to be just a misprint with the "n".: )
If anyone can clear one small thing up for me. was he saying that for most of a cells life it is coding for proteins and shortly before cell division it takes the shape of chromosomes?
I don't know why but I can't help but be happy when I watch these videos. It's different then the atmosphere at school, there is a sense of care in your voice, its almost like a family member is teaching me and not a person being paid a small amount of money. yeah.
I Really appreciate your great charity work for all of us, confused students looking for an angel to descend on us and explain the dark confusion... May force be with you always, and may your knowledge lit up your way brighter and brighter every day...
I have checked your videos and would be looking forward to see more from you...
dude your amazing. I just wanna give you a huge kiss! i have an exam on this on monday so im studying my ass off trying to read a book because my teacher cant teach for shit, im so happy i found your videos! you might have just got me an A :D wish me luck
your video makes no sence. you say something and say something in a totaly diferent way. you are confusing i have to think about it and restate it to make it make sence.

@spike378 kinetochore is a protein that's attached to the centromere. The microtubules attach to the kinetochore during mitosis or meiosis to put either the chromosome or chromatids apart =)
@spike378 well, if you want to get technical, you could say that there's millions of proteins since you have millions of histones in a chromosome, you have the centromere that holds the homologous chromosomes together, and then you have the kinetochore that's attached to the centromere. Without the kinetochore, the microtubules won't be able to attach and well, mitosis and meiosis won't occur.
@xtxaxnxtxyxa sorry, I need to make a correction. The centromere is the region where the two chromatids are attached. The protein that holds them together is cohesin.
I love your video! you cleared everything up for me. I feel much better about my upcoming bio exam now. You did a great job in explaining everything so clearly, especially your drawings made complicated things seem much easier.
loved the video. I was studying for a bio exam and something he explained wasn't clear. I spent an hour in lecture and you spent 18 minutes explaining this clearer than my professor. good stuff.
wow .... simple yet so informative ... this lecture beats all those fancy animations .... best video ... thanks so much ... also you are very well in speaking ...neither too slow nor too fast ,....
this clears thing up so much... i have two huge bio textbooks, notes from 2 different teachers, notes from my senior, and none of them explained the difference between chromosomes,chromatin and chromatids...
thanks for explaining the vacab esp for chromatin, chromosomes, and chromatids!!! i am having a test this afternoon on this and i'm not having a nervous breakdown over this.
I love your videos your a really good teacher....thanks for sharing your talent....wish you were my bio teacher....he skips so much cause he just expects us to know this stuff.... really sucks but you make my life so much better ^_^ love you....!!!!!
I think the part about chromatids is erroneous. They are not in paternal/maternal pairs, they are in pairs of identical duplicates.
