nasty-shy [4]

Answer:

362 nucleosomes

Explanation:

A nucleosome repeat is made up of the DNA (146 bp) wrapped around the core nucleosome particle and the linker DNA (110 bp as in this situation). We can conclude that, every repeat stands for 256 (146 + 110) base pairs of DNA.

We are given the length of the entire region to be 92,672 bp long,

To determine the number of nucleosomes to organize the region into the 10nm fiber structure

Let,

Number of nucleosomes =

the length of the entire region

------------------- -----

base pairs of DNA.

= 92,672

-------

256

= 362 nucleosomes

Therefore, 362 nucleosomes is needed to structure the region into the 10nm fiber structure.
