Answer» Correct Answer - B In prokaryotes, a single mRNA molecule may code for one or several polypeptide chains . If it carries the code for only polypeptide the mRNA is monocistronic and if it codes for two or more different polypeptides the mRNA is polycistronic in eukaryotes most mRNAs are monocistronic Termination codons like UAA, UGA, UAG etc. are present on mRNA and capable to release the polypeptide chain
