Answer:

The correct answer will be option- A.

Explanation:.

Histone demethylases are the enzymes which controls the gene expression of any gene. These enzymes play an important role in epigenetic control of gene. The post-translational modifications like methylation and acetylation changes the structure of the chromatin which alters the interactions of the chromatin.

The histone demethylase removes the methyl group from the histone tails which causes the condensation of the loose chromatin structure to form heterochromatin.

Thus, option-A is the correct answer.

Why might the cellular response to a peptide hormone be expected to be rapid compared to the cellular response to a steroid horm
topjm [15]
Peptide hormones are usually produced in the body ahead of the time when they will be required. They are usually synthesized in the inactive form and store in the secretory vesicles just under the plasma membrane. Stimulation of the signalling causes immediate release of these hormones into the surrounding medium or the blood. Thus, cellular response to a peptide hormone is always rapid compared to that of the steroid hormone.
