Main Question or Discussion Point

Hi all,

I was just wondering, what stimulus activates protein synthesis? I already know the steps of protein synthesis but is there a particular mechanism that triggers the RNA polymerase to start transcription? In other words, how does the body know when to produce proteins? Is it possibly with hormones?

Many thanks,
Jay

Protein synthesis is controlled by transcription factors that bind to DNA to either promote or repress transcription.

Here's a chapter from Albert's Molecular Biology of the Cell giving some examples of how various signals can turn genes on and off in bacteria and eukaryotes:
