Answer:
Lysine
Step-by-step explanation:
Lysine is an amino acid (the protein main component). It is used by individuals to make medication. Lysine (triggered by the virus called herpes simplex labialis) is used to avoid and manage cold sores.
For this reason, it is taken by mouth or applied directly on the body.
Histone acetylation and deacetylation are the processes that acetylate and deacetylate the lysine residues within the N-terminal tail protruding from the nucleosome's histone center as result of gene expression.
