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.

1. What is a double helix?
RUDIKE [14]

Answer:

1. Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.

2. The DNA double helix. The two sides are the sugar-phosphate backbones, composed of alternating phosphate groups and deoxyribose sugars. The nitrogenous bases face the center of the double helix.

3. A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

4. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

5. In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA

Hopes this helps.
