"WebA given enhancer may not be capable of accessing the entire genome as a possible target, which could be considered a hallmark of a truly trans-acting factor. Rather, enhancers function locally without dissociating from chromatin (either looping to its promoter target or tracking). This necessitates an overall designation of cis-acting.

Though these two … WebTranscription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.

WebAug 31, 2024 · Enhancers work like genetic switches: to turn a gene on, proteins called transcription factors assemble on an enhancer. Each transcription factor recognises a short sequence on the enhancer, and several distinct transcription factors work together to promote the activatation of a gene.
