Translation
Notion of “gene expression”

Question: Why aren’t “identical twins” identical?

Epigenetics
From Wikipedia:
“Epigenetics is the study of heritable changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence.”

Is epigenetics why cloned animals don’t fare well?

Genetic regulation

Genetic Switches (in “non-expressed” regions)
