transcription activation

Transcription activation is the process by which specific proteins called activators enhance the production of messenger RNA (mRNA) from a gene's DNA. Activators bind to specific regions of DNA near a gene, called promoters or enhancers, helping to recruit the cell’s machinery responsible for copying DNA into mRNA. Think of it as a switch that turns on the gene’s activity, ensuring the cell produces the right proteins when needed. This regulation is crucial for controlling gene expression in response to different signals and maintaining proper cell function.
