The control of gene expression is essential for life. It determines which genes are turned on or off in a cell. Several mechanisms regulate gene expression, including transcriptional, post-transcriptional, translational, and post-translational control. Disruptions in gene expression can lead to diseases. Understanding gene expression is crucial for developing new treatments.
