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.

There are positive and negative charges. Look at is this way a charge attracts a positive charge. On the other hand, when a charge is brought near a distributed charge, high is your hair for this, the positive charge attracts the negative charge so opposite charge concentration increases in the hair. So, when the same type of charge is in the hair, the hair stands up.
