Hello students, in this question we have a upeeriotic zine.
00:07
And this leucuriotic zine is 2 ,000 base pairs in length.
00:17
And they are asking about the number of copies of installed h4 present in this season and number of copies of h1 present in this particular nature.
00:32
So first of all, h4 and h1 both are pistols.
00:39
These stones are responsible for first level of dna packages.
00:52
These histones are positively charged and we know that our dna is negatively charged due to the phosphate web.
01:16
So this negatively charged dna is backed around the histones.
01:20
Octumal and so that it can come in the small size nucleus so first of all what is nucleosome so these stones can be gold stone and lincoln stone in four stone we have h2a h2b h2b h3 and h4 these are the cold stone lincoln stone we have hatchment generally.
02:01
So these four histones are, in these four histones, 147 base pair of dna wept around these four histones.
02:19
Now when we are talking about nuclear zone, the nuclear zone is histone, histone, plus dna wept around this histone octum.
02:48
So suppose we are having, when this is stone of number, i am going.
03:09
Okay, so this is our stone of number.
03:12
Here we have h2a, h2b, h3, h3, x4, and then again, h2a, and then again h2a, h2b.
03:29
H2a, h2b for dimers, when the h3h4 form that's number.
03:41
This is in store of number.
03:53
So suppose we are having several stores and several nuclezone.
04:01
Suppose this is one nucon, this one is another nphal and here this is another.
04:12
These are histone octamer and dna is webbed around them.
04:29
Dna is webbed around them and stone.
04:39
So these are nucleosone.
04:42
This histone october.
04:52
Plus dna.
04:56
This is nuclear zone...
