Epigenetic regulation refers to the processes that modify gene expression without altering the underlying DNA sequence. This regulation involves mechanisms such as DNA methylation, histone modification, and non-coding RNA molecules that can turn genes on or off, influencing cellular functions and development. Through these processes, epigenetic regulation plays a critical role in genomic imprinting, where specific genes are expressed in a parent-of-origin manner, contributing to various biological phenomena and diseases.
