Vedclass · Answer

(A) The $lac$ operon is a polycistronic unit,meaning a single $mRNA$ molecule encodes multiple proteins. Specifically,the $lac$ $mRNA$ encodes three enzymes: $\beta$-galactosidase $(lacZ)$,permease $(lacY)$,and transacetylase $(lacA)$. Because it is polycistronic,the $lac$ $mRNA$ contains multiple initiation and termination codons to facilitate the translation of these distinct polypeptide chains.
