Gene regulation is the process by which cells control the expression of their genes. This means that not all genes are active at all times; instead, cells can turn genes on or off as needed. This regulation is crucial for processes like development, response to environmental changes, and maintaining cellular functions. Various mechanisms are involved in gene regulation, including transcription factors, enhancers, and silencers. These elements interact with the DNA to either promote or inhibit the transcription of specific genes. By regulating gene expression, cells can adapt to their surroundings and perform specialized functions.
