Phrases with «promoter sequences»

Promoter sequences are specific regions of DNA that control the initiation of gene expression. They act like a "start" button, telling the cell when and where to begin reading the instructions (or genes) encoded in DNA. Promoter sequences play a crucial role in determining which genes are turned on or off in different cells or at different times, ultimately influencing various biological processes. Full definition
