When DNA is compacted by histones into 10-nm and 30-nm fibers,
the DNA is unable to interact with proteins required for gene
expression. Therefore, to allow for these proteins to act, the
chromatin must constantly alter its structure. Which processes
contribute to this activity?
a.
nucleotide removal
b.
hydrolysis of DNA molecules where they are wrapped around the
nucleosome core
c.
DNA coiling at or around H1
d.
accessibility of heterochromatin to deacetylase enzymes
e.
acetylation of histone proteins
