gene regulation
Quick Summary
Gene regulation is the process by which cells control which genes are turned on or off, influencing protein production. This is crucial because different cell types have the same genes but express different ones, leading to specialized structures and functions.
Gene action can be activated or deactivated based on the cell's developmental stage and its environment. This regulation occurs at multiple levels, starting with transcription, where DNA is copied into RNA. Regulatory proteins, such as activators and repressors, bind to specific DNA regions to either promote or block transcription.
In eukaryotes, unlike prokaryotes, genes are regulated individually. Further control happens during RNA processing, including splicing, and at the translational and post-translational levels, ensuring the correct proteins are synthesized and function properly.123
