What is the Origin of Epigenetics?

The term "epigenetics" was coined in the 1940s by Conrad Waddington, combining the Greek prefix epi- (on, above, or in addition to) with "genetics." Waddington used it to describe the developmental processes that mediate the relationship between genotype and phenotype. Modern molecular biology has since defined the precise chemical and structural modifications responsible for this level of gene regulation, moving the concept from a theoretical framework to a molecular reality.

What is the Mechanism of Epigenetics?

Epigenetic regulation operates through several key molecular mechanisms, including DNA methylation, histone modification, and non-coding RNA-mediated silencing. DNA methylation typically suppresses gene transcription by adding a methyl group to cytosine bases, while histone acetylation generally opens chromatin structure, making genes more accessible for transcription. These reversible chemical tags dynamically respond to hormonal cues and environmental factors, allowing the genome to adapt its expression profile to the immediate physiological environment.

Epigenetics

Meaning

Epigenetics is the study of heritable changes in gene expression that occur without an alteration to the underlying DNA sequence itself. These modifications act as an interface between the environment and the genome, determining which genes are turned on or off in specific cells and tissues. Epigenetic mechanisms are profoundly influenced by lifestyle, diet, stress, and hormonal signaling, offering a dynamic layer of control over genetic destiny and contributing significantly to health and longevity outcomes.
