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.
In constitutive mutants, the lac operon genes are continuously transcribed. A mutant regulator gene (lacI -) produces a defective repressor that cannot bind to the operator. A mutant operator region (lacO c) is defective in that the repressor cannot bind and thus transcription cannot be shut off.Both types of mutants have the same constitutive phenotype. mutant regulator gene (lacI -) produces a defective repressor that cannot bind to the operator.
