Question

How many nucleosome present in a bacterial cell if it contain 2×10^3 base pair in their DNA molecule ​

Answer 1

Answer:

2 pair of bacterial cell in present it ok

Answer 2

Nucleosome present in a bacterial cell:

A nucleosome is a part of DNA that is wrapped around the 8 pieces of histone proteins which are also called a histone octamer and contain 1.75 turns of the histone protein.  

This 1.75 turn of the DNA contains about 146 base pairs of the nitrogen bases of the DNA

So, in a DNA having $2 \times 10^{3}$ base pairs, number of nucleosomes  

$=2 \times \frac{10^{3}}{146}=13.69$

So, around 13 nucleosomes are present in the DNA with 2000 base pairs of nitrogen bases.
