Which one of the following statements concerning prokaryotic gene epression is INCORRECT ? a) Binding site for a repressor protein often overlaps with the promoter thereby blocking binding of RIXA polymerase binding b) A large fraction of genes are not part of operons

Which one of the following statements concerning prokaryotic gene epression is INCORRECT ? a) Binding site for a repressor protein often overlaps with the promoter thereby blocking binding of RIXA polymerase binding b) A large fraction of genes are not part of operons . ( ) Each operon produces one MRNA containing multiple protein coding regions, translation of which ensures equal number of polypeptides from each gene in the operon. d ) Translation often starts before MRNA synthesis is complete.
