(D) In prokaryotes,transcription occurs in the cytoplasm,and because there is no nuclear membrane,it is often coupled with translation. Prokaryotic mRNA does not require splicing,capping,or tailing (polyadenylation). Therefore,statement $(a)$ and $(b)$ are correct,while statement $(c)$ is incorrect because capping is not essential in prokaryotes. Thus,only $(c)$ is incorrect.

Prokaryotic transcription mechanism requires the involvement of only one polymerase type and:
$(a)$ It occurs in the cytoplasm only.
$(b)$ It is often coupled with translation.
$(c)$ It does not require splicing but capping is essential.

A
All are correct.
B
Both $(b)$ and $(c)$ are incorrect.
C
Both $(a)$ and $(c)$ are correct.
D
Only $(c)$ is incorrect.
