genetic silencers

Genetic silencers are DNA elements that can decrease or block the activity of specific genes without altering the gene itself. They act like switches that turn gene expression down or off, often by influencing how tightly DNA is packed or by preventing the gene’s signals from being read by the cell's machinery. This regulation helps ensure genes are active only when needed, maintaining proper cell function and development. Silencers are an important part of the complex system that controls which genes are expressed in different cells and conditions.
