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.
2 Regulation can be negative or positive. 1  A repressor is a protein that inhibits expression of a gene. 2  It may act to prevent transcription by binding to an operator site in DNA, or to prevent translation by binding to RNA. A repressor is a protein that inhibits expression of a gene. 2  It may act to prevent transcription by binding to an operator site in DNA, or to prevent translation by binding to RNA. 3  The operator is the site on DNA at which a repressor protein binds to prevent transcription from initiating at the adjacent promoter.
