Chromosome Structure and Organization

We've all seen pictures of chromosomes, and we know that they contain DNA. But how do we get from the double helix of DNA to the X-looking shape of a chromosome? Is it just DNA, or are there other things in there? How much DNA is in each chromosome? Chromosomal structure is incredibly complicated, but now that we've learned about DNA and proteins, as well as Mendelian genetics for a little context, we are finally ready to get a more sophisticated view of what's inside a chromosome.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

I really wish I found these videos months ago instead of 2 days before my genetics final lmao

I love you Professor Dave! I can't express much how grateful I am for all your effort in making these comprehensive contents in different fields of Natural Science. I am currently taking my Grad studies and I am literally stuck with all the concepts we are learning in class for I don't have a strong grasp of the basic concepts in Biology, Biochem and Chemistry. With your videos, I'm slowly recovering and retaining all the information I have learned way back in my undergrad. Thank you so much. May the Almighty bless you more. (:

Easy to understand :) I like how you talk slowly and give your audience time to comprehend.

You're videos don't have the amount of views they are worth. I will recommend to my friends in the future. Keep up the good work, more views will come in time seeming your channel is still fairly new.

Chromosomes are nearly as information-dense as this lovely video. Thanks Professor Dave!

[harshsinghal]

such a great video. many many thanks.
please keep uploading biology videos.

You're going to be the reason I pass my genetics class.

Professor 👨‍🏫 Dave you are the science 🧬 GURU

[RODRIGOALONSOGAETEGEISSBUHLER]

you're just excellent at teaching. Thanks!

[codewithayesha]

Thanks, sir, that was a great explanation and it helped me a lot to make my concepts better.

Are chromosome actutally in that shape, like an x or an an I and floating inside the nucleus?

[shahrzadmazoury]

Easy to understand, and informative ! Thanks

[OtnerNangula]

awesome prof, , , now that we are herding to exams would you plz send me some past AS-level questions to reviase on????

[christianemile]

Oh, thank you Dave! I finally get X-linked genetics now.

Question: so the DNA genome is 3 billion base pairs? and those base pairs are divided up into the 46 chromosomes in each cell? Thanks in advance
