Question

Alteration of histones by addition of methyl and acetyl groups to particular amino acids Question 9 options: changes B-DNA to Z-DNA.results in the remodeling of chromatin that can activate or inhibit gene expression. creates G bands seen after Giemsa staining of chromosomes. helps preserve telomeres during DNA replication.

Answer 1

Answer:

Results in the remodeling of chromatin that can activate or inhibit gene expression

Explanation:

Alteration of histones by addition of methyl and acetyl groups are examples of chromatin remodeling complexes. These allows for the remodeling /alteration of the chromatin state to allow transcriptional machinery and other cellular processes to have access to the DNA. This way, they can either activate or inhibit gene expression. Methylation patterns inhibits gene expression while acetylation activates gene expression and so on.
