Regulation of gene expression

Regulation of gene expression is the process by which cells control when and how genes are turned on or off. This ensures that the right proteins are made at the right times and in appropriate amounts, allowing cells to respond to their environment and perform specialized functions. It involves mechanisms such as turning genes on or off through chemical signals, modifying DNA or associated proteins, and controlling the activity of the molecules that read genes. This precise control is essential for development, health, and adaptation in all living organisms.
