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.
An unidentified prokaryotic cell. Thus, option "4" is correct.
<h3>What atr prokaryotes and eukaryotes?</h3>
Prokaryotes are the unicellular organisms that do not contain nucleus and membrane bound organelle in their cell. Their genetic material is present in the cytoplasm.
On the other hand, eukaryotes have true nucleus that contains the genetic material (DNA). They also contain membrane bound specialised organelles (such as mitochondria, endoplasmic reticulum, golgi complex).
Thus, option "4" is correct.
