Epigenetics
Epigenetics, a field nestled within the realms of genetics and molecular biology, unveils the intricate dance between genes and the environment. Unlike traditional genetics, which focuses solely on DNA sequences, epigenetics illuminates how external factors can influence gene expression without altering the underlying genetic code. Through mechanisms like DNA methylation and histone modification, epigenetics provides a profound understanding of how our experiences, lifestyle choices, and environmental exposures can leave molecular imprints on our genetic material, shaping not only individual health outcomes but also offering insights into inherited traits and disease susceptibilities.
