Some viruses attack cells by inserting their own DNA into the host cells' DNA. Why might it be simpler for these viruses to attack prokaryotic cells than eukaryotic cells?
A. Prokaryotic cells have less DNA than do eukaryotic cells.
B. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
C. The cell wall in prokaryotic cells is a less effective barrier.
D. The rapid growth of prokaryotic cells generates more virus.

which phylogenetic tree is consistent with most current hypotheses, the one based on characters or the one based on DNA?
In other words,
Why isnt the DNA digested with the second restriction enzyme for all the individuals, but only some ?
How could one change in a DNA nucleotide alter the formation of the translated protein?
