Vedclass · Answer

(D) In prokaryotes:$A$. Prokaryotic structural genes are typically polycistronic,not monocistronic. Thus,statement $A$ is incorrect.$B$. Prokaryotic genes do not contain introns (non-coding sequences). Thus,statement $B$ is correct.$C$. Since there is no nuclear membrane,transcription and translation occur in the same compartment and are coupled. Thus,statement $C$ is correct.$D$. Splicing is a process required to remove introns from eukaryotic pre-mRNA. Since prokaryotes lack introns,they do not undergo splicing. Thus,statement $D$ is incorrect.$E$. Prokaryotes possess only a single type of $RNA$ polymerase that transcribes all types of $RNA$ $(mRNA, tRNA, rRNA)$. Thus,statement $E$ is correct.Therefore,statements $B, C$,and $E$ are correct.
