How many nucleosomes are present in DNA of a human cell?

Options:

Answer:
D
Solution:

In a human cell, the length of DNA molecule is about2.2 meter, in which about6.6×109base pairs are present. This DNA is present along with histone protein in the form of 'Beads on string', which is called as a nucleosome. Each nucleosome carries 200 base pairs. So number of nucleosomes=6.6×109/200=3.3×107.
