What is "gene expression"?

• process by which DNA makes a copy of itself during cell division.
• the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins
• processes that convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP),
• the process by which the instructions in our DNA are converted into a functional product, such as a protein.

The prefix epi means "on top of." What is "epigenetics."

• Changes in gene expression that do not involve changes to the DNA sequence
• Changes in gene expression that are due to mutations of the DNA sequence
