Bacteria also use translational
control of enzyme synthesis. In this case, the bacteria produce noncoding RNAs (ncRNAs) or antisense
RNAa such as microRNAs (miRNAs) that are complementary to an early portion of the mRNA coding for the enzyme. When the noncoding
RNA binds to the mRNA by complementary base pairing, ribosomes cannot attach, the mRNA cannot be
translated into protein, and the enzyme is not made.
