29. If a cell has accumulated DNA damage, it is unlikely to (A) pass the G2 checkpoint (B) activate DNA repair mechanisms (C) enter G1 from mitosis (D) synthesize cyclin-dependent kinases

8. The acetylation of lysines on the histone tails... (A)loosens chromatin structure by adding positive charges to histones. (B) recruits the heterochromatin protein HP1, resulting in the establishment of heterochromatin. (C) can be performed on methylated lysines only after they are first demethylated.
