Gene Expression Regulation

Meaning

Gene expression regulation is the intricate cellular process that controls which genes in a cell’s DNA are transcribed into functional products, such as proteins or non-coding RNA, and at what level. This dynamic control mechanism allows cells to respond precisely to their internal and external environments, ensuring differentiation, adaptation, and homeostasis across all life stages. It is the fundamental biological process that determines a cell’s structure and function, directly influencing hormonal signaling and metabolic health. Errors in this regulation are often central to the development of chronic disease and the aging process.
