You will need a ride home after the procedure because of the medicines or anesthesia you received. Coronary angiography is a common procedure that rarely causes serious problems. Possible complications may include bleeding, allergic reactions to the contrast dye, infection, blood vessel damage, arrhythmias, blood clots that can trigger a heart attack or stroke, kidney damage, and fluid buildup around the heart.
(Redirected from Corepressor (genetics)) In the field of molecular biology, a corepressor is a substance that inhibits the expression of genes. In prokaryotes, corepressors are small molecules whereas in eukaryotes, corepressors are proteins. A corepressor does not directly bind to DNA, but instead indirectly regulates gene expression by binding to repressors.
As with all operons, the trp operon consists of the repressor, promoter, operator and the structural genes. In this system, though, unlike the lac operon, the gene for the repressor is not adjacent to the promoter, but rather is located in another part of the E. coli genome.Another difference is that the operator resides entirely within the promoter.n this system, though, unlike the lac operon, the gene for the repressor is not adjacent to the promoter, but rather is located in another part of the E. coli genome.
