Which of the Following Best Describes the Histones Associated with Eukaryotic

Which of the following best describes the histones associated with eukaryotic DNA?

A) Along a 10,000 base pair segment of DNA, you expect to find twice as many molecules of histone protein H1, as histone protein H4.
B) The amino acid sequences of H4 vary extensively.
C) Within the nucleosome core particle, H1 is the most conserved and crucial histone protein.
D) The five types of histone proteins are small, basic proteins with a positive charge that allows them to bind to DNA.
E) Thousands of base pairs of DNA often wrap around each nucleosome core particle more than a dozen times.
