Epigenetics
Definition of Epigenetics as it relates to Science, Genetics, Chromosomes
Epigenetics refers to modifications on DNA and histone proteins that do not alter the genetic code but can influence gene expression, often in response to environmental factors. These changes can be heritable and play a crucial role in cellular differentiation, development, and disease processes, including cancer and aging. In the context of chromosomes, epigenetics encompasses mechanisms that regulate chromatin structure and accessibility, thereby controlling gene transcription and genome stability.
