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.
biochemistry. 1  a protein synthesized under the control of a repressor gene, which has the capacity to bind to the operator gene and thereby shut off the expression of the structural genes of an operon. 2  something that represses; esp., a protein produced in a cell that prevents the synthesis of a specific enzyme.
