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. WebGenes encode proteins, and the instructions for making proteins are decoded in two steps: first, a messenger RNA (mRNA) molecule is produced through the transcription of DNA, and next, the mRNA ...
