Question

Alteration of histones by addition of methyl and acetyl groups to particular amino acidsA) alters the denaturation and renaturation of DNA.B) creates G bands seen after Giemsa staining of chromosomes.C) helps preserve telomeres during DNA replication.D) results in the remodeling of chromatin that can activate or inhibit gene expression.E) changes B-DNA to Z-DNA.

Answer 1

Answer:

D) results in the remodeling of chromatin that can active or inhibit gene expression

Explanation:

DNA methylation results in the tighter, euchromatin version of DNA that is harder to transcribe; its counterpart DNA acetylation results in the DNA becoming looser and easier to transcribe.
