Answer:

nucleosomes = 1.65 x 10^6

H2a = 3.3 x 10^6 molecules

H2b = 3.3 x 10^6 molecules

H3 = 3.3 x 10^6 molecules

H4 = 3.3 x 10^6 molecules

Explanation:

It was mentioned in the book Principles of Genetics  By D. Peter Snustad, Michael J. Simmons that in the nucleus of <em>D. melanogaster </em>there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.
