activators

Activators are molecules that initiate or speed up a biological process, often by binding to specific sites on a target, such as DNA or enzymes. In gene regulation, activators bind to DNA near genes to increase their expression, helping cells produce necessary proteins. They serve as positive signals, turning certain functions on when needed. Think of activators as biological switches or catalysts that help ensure processes happen efficiently and at the right time, contributing to the proper functioning of cells and organisms.
