Question: A diploid nucleus of Drosophila melanogaster contains about 3.4 x 108 nucleotide pairs. Assume (1) that all nuclear DNA is packaged in nucleosomes and (2) that an average internucleosome linker size is 60 nucleotide pairs. How many nucleosomes would be present in a diploid nucleus of D. melanogaster? How many molecules of histone H2a, H2b, H3, and H4 would be required?
ANS: In the diploid nucleus of D. melanogaster, 1.65 x 106 nucleosomes would be present; these would contain 3.3 x 106 molecules of each histone, H2a, H2b, H3, and H4.
So I know this is the answer, but I am having a hard time understanding why and how to obtain this answer. Any help would be appreciated. This is for my genetics class by the way.

Why would changes in the genes for transcription factors be expected to generate major phenotypic differences? They are extremely powerful genes. They can affect the expression of small numbers of other genes. Their gene products are remarkably stable. Their gene products normally denature more rapidly than other gene products. They can affect the expression of large numbers of other genes. Which enzyme, also responsible for siRNA formation, carves miRNAs from their double-stranded, fold- back RNA precursor (pre-miRNA)? Dicer ribonuclease RNA...
