Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

RUDIKE [14]

Answer:

Coronavirus in its own doesn't have an advantage.

I believe that it helps us to prevent other epidemic diseases such as cholera and other diseases that are caused by lack of sanitization.

Since washing hands frequently is the way of preventing coronavirus.

And wearing mask also helps us to prevent other respiratory diseases being transmitted.
