A STUDY ON DIFFERENTIATED OF EPIGENETICS AND GENETICS

Epigenetics refers to heritable phenotypic changes that do not alter the DNA sequence but arise from modifications in chromatin structure. These modifications, including histone alterations and DNA methylation, shape the epigenetic profile, influencing cell memory, fate, and mammalian development. Unlike the static genetic code, the epigenetic code is dynamic, varying across tissues and over time due to aging, disease, or environmental factors. Ongoing research explores the interplay between histone modifications, DNA methylation, and RNA interference in contexts such as cancer, X chromosome inactivation, and genomic imprinting.
