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.

What male reproductive structure releases sperm into the vas deferens?
lisov135 [29]

The answer is epididymis.

<span>Testicles contain seminiferous tubules, in which sperm is produced, and an epididymis, in which sperm matures. Mature sperm passes through the epididymis to the vas deferens. There, it combines with a liquid secretion from the seminal vesicles and continues through the prostate gland to the urethra. Sperm containing fluid is called semen and it is ejected through the urethra.</span>

Los temas.<br> 1. ¿La Meiosis es la división propia de células?
Setler [38]

Answer:

Explanation:

Al igual que la mitosis, la meiosis es una forma de división celular eucariota. Sin embargo, estos dos procesos distribuyen el material genético entre las células hijas resultantes de formas muy diferentes. La mitosis crea dos células hijas idénticas, cada una de las cuales contiene el mismo número de cromosomas que su célula madre.
