Antisense RNA

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.
