So the question here is asking that genes are connected in a long dna and protein structure called blank and are composed a material called blank, composed of what material? so the answer here we have to think about is how is dna really packaged? that's essentially the question.
00:27
So we have double helix dna, right? that is in its essence.
00:33
Really down into it, that's what dna is looking like.
00:36
However, this is super -quil, right? because dna is super -long, and if it's not super -coiled, there is no way that our cells can house all of this dna.
00:46
And so it's super -coiled around what? so it's super -coiled around these protein structures and these protein structures.
01:20
So what are these protein structures called, essentially? these are nucleosomes.
01:32
And when we have a string of these nucleosomes essentially packaged together, we have a string of these packaged together.
02:01
This complex is called chromatin.
02:11
And when we have a bunch of chromatin fibers, or really what's known as a chromatin fiber, we have a bunch of these coiled together...
