Gene Regulation

Gene regulation encompasses the wide array of mechanisms that cells use to control the expression of genes, selectively turning them on or off and modulating the amount of protein or functional RNA produced. This precise control is fundamental for cellular processes such as differentiation, allowing a single genome to give rise to diverse cell types like neurons and muscle cells, and for enabling organisms to respond and adapt to changes in their environment. Regulation can occur at multiple levels, including the initiation of transcription through the action of transcription factors and epigenetic modifications, post-transcriptional processing of RNA, and the control of translation and protein stability.
