One Consequence of the Lack of Introns in Bacterial Genes

Question

One consequence of the lack of introns in bacterial genes is that
A)exons are eliminated during transcription.
B)a 5' cap and poly (A)tail can be added immediately.
C)bacterial proteins are very short and not subject to mutation.
D)translation can begins before transcription is complete because prokaryotes do not have a nucleus.
E)integrated viral DNA is not recognized for transcription.

Accepted Answer

In bacteria, which are prokaryotes, the absence of a nucleus allows for the processes of transcription and translation to occur simultaneously. This is because there are no introns to remove from the mRNA, and the mRNA does not need to be transported out of a nucleus before translation can begin. This simultaneous process is not possible in eukaryotes, where transcription occurs in the nucleus and translation occurs in the cytoplasm, necessitating the complete processing of mRNA (including splicing out introns) before it can be translated.
