Promoter regions

Promoter regions are specific sequences of DNA located near the start of a gene. They serve as essential control sites that help initiate the process of gene expression, which is how information in DNA is used to produce proteins. Proteins carry out various functions in the body, so promoters play a crucial role in regulating when and how much of a protein is made. Essentially, they act like switches, turning genes on or off, thereby influencing how cells behave and respond to their environment.
