The length of linker DNA segments varies somewhat among organisms. The length of the linker DNA in sea urchin is 110 base pairs.
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.

Iteru [2.4K]

Answer:

Basic Research

Explanation:

The initial discovery and analysis of the Lake Vida bacteria allowed them to be classified thereby leading to an understanding of their basic metabolic processes.

Although ,the introductory passage suggested several ways that this could lead to applied research by allowing the development of new products.

Conclusively, the research is a basic in nature because it gave a better understanding of the natural world.
