Question

An example of a type of modification that takes place on histones that appears to modify the levels gene transcription is

a. acetylation
b. phosphorylation
c. methylation
d. ubiquitination
e. all of the above

Answer 1

Histone acetylation, phosphorylation, and methylation are modifications that can affect the levels of gene transcription on histones.

Step-by-step explanation:

One example of a type of modification that appears to modify the levels of gene transcription on histones is acetylation. Histone acetylation tends to unwind nucleosomes and open the underlying DNA for transcription. Another modification is phosphorylation, which can alter translation, RNA shuttling, RNA stability, or post-transcriptional modification. Additionally, methylation of histones can either open or suppress DNA for transcription, depending on the specific lysine or arginine being methylated.
