Alteration of histones by addition of methyl and acetyl groups to particular amino acidsA) alters the denaturation and renaturat
ion 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.
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.
