    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!

    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!

    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.

    whats amazing of these videos is that if you turn on caption, the subtitles are so matching and so accurate when he speaks

    @Alexxyk Před 12 lety +29

    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 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

  • @felixreininghaus2808
    @felixreininghaus2808 Před 3 lety

    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.
