Maternal Effects and Epigenetics

Vocabulary practice flashcards covering maternal effects, genotypes, and epigenetic modifications based on the lecture transcript.

Epigenetics

DNA modifications that do not alter the base pairs, but change how DNA is expressed and alter its accessibility.

Methylation

A type of mark or modification on DNA that can change its accessibility and expression without altering the base pairs.

Epi-

A prefix referring to an addition on top of the DNA, rather than something baked directly into the base pair sequence.
