What Histone Modifications are Associated with DNA Repair

Question

What histone modifications are associated with DNA repair?
A) H3K27 acetylation
B) H3K79 methylation
C) H2B ubiquitination
D) H3K27 acetylation and H2B ubiquitination
E) H3K79 methylation and H2B ubiquitination

Accepted Answer

H3K79 methylation and H2B ubiquitination are both associated with DNA repair processes. H3K79 methylation is linked to the recruitment of repair proteins, while H2B ubiquitination is involved in chromatin remodeling necessary for repair.
