Some proteins are produced only when needed. this is an example of gene regulation that conserves energy.
What is gene regulation?
The mechanism by which genes are regulated affects when, where, and how much they are expressed. Regulational proteins and chemical modifications to DNA are just two of the many mechanisms that can be used to carry out the process, which can be intricate.
What protein is involved in gene regulation?
Activator proteins bind to DNA regulatory sites close to promoter regions, which serve as on/off switches. The RNA polymerase activity and transcription of neighboring genes are made easier by this interaction.
