D) changes in gene expression due to genetic effects rather than environmental effects.

Question

Quizplus · Accepted Answer

Epigenetic regulation involves changes in gene expression rather than a change in the encoding region in a gene. It refers to modifications in the chromatin structure that alter the accessibility of DNA to transcription factors, and other regulatory proteins, without affecting the DNA sequence itself. These modifications can be heritable, meaning that they can be passed on from one cell to another during cell division and, in some cases, from one generation to the next.
