go to 9:00 to go directly to the chromosome, chromatid, chromatin part
-
I could cry, this channel is great. You guys are making people's lives better.

i like when he bugs himself as he's writing something and just continue to repeat the same thing over and over: "Transcription... transcription... trans.. scription... transcription! Transcription". Shock teaching, very effective. Amazing video!
-
what make you a good teacher is your ability to identify the parts which are confusing to the students. thank you!
-
My geezus! Week 6 of a 8 week Biology class and I finally understand what in the heck the differences of the 3 C's are! I swear if I could go teleport, I would, just to look you in the eye and say...THANK YOU!
-
whats amazing of these videos is that if you turn on caption, the subtitles are so matching and so accurate when he speaks
-
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!

A chromatid is just the compact form of chromatin. It only has this form when cells divide. Most of the time it's not in this compact form. Then the chromatin lies in a very shambolic way in the nucleus. In this form the DNA is far more accessible for enzymes to do their job on the DNA.

This literally made me start crying as soon as I started getting it, thank you so much!!
-
So brilliant!! I was struggling with the 3 chromos, but it makes so much more sense now!! Thank you!!!
-
Fantastic way of teaching a very difficult subject to the students. From a former professor in Medical college.
-
Thank you. The fact that they can refer to different things and it doesn't entirely make sense made this make so much more sense. My biology professor just never bothered properly explaining the usage of those terms.
-
I am impressed as to how quickly and clearly the guy was able to write stuff down through a mouse/ touchpad.
-
Can't believe this video is 11 year ago 😳
-
This is really helping me with biology. I’ve watched at least 10 or more videos. Thank you
-
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
-
Very nice work! I think it's acutally hard to explain all this stuff in an understandable way, but you did a great job!
-
I like how you bring all the little things I've learned and put it in a larger picture. Thanks.
-
Thanks that's extremely helpful & clears up a lot of the confusion around all these terms...

You are literally a life saver. Huge exam tomorrow and finally understand. Thank you so much !
