Many times (at least several times a week) I would feel a lot of air in my stomach - mostly after eating or drinking soda or whatever. It was okay for a while, but I didn't think it was normal for me to produce that much gas in my stomach and for me to be unable to burp.
In molecular genetics, a repressor is a DNA-or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers.
As in prokaryotes, eukaryotic repressor molecules can sometimes bind to silencer elements in the vicinity of a gene and inhibit the binding, assembly, or activity of the transcription complex, thus turning off expression of a gene. Positive regulation by TFs that are activators is common in eukaryotes.
