36. A nonsense mutation in a gene (A) changes an amino acid in the encoded protein (B) has no effect on the amino acid sequence of the encoded protein (C) introduces apremature stop codon into the mRNA (D) alters the reading frame of the mRNA

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. (D) is a covalent modification and is thus irreversible.
