Both Assertion and Reason are True and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) In bacteria,the genetic material is not enclosed within a membrane-bound nucleus; it is present in the cytoplasm.Because there is no nuclear membrane,the processes of transcription (synthesis of $	ext{mRNA}$ from $	ext{DNA}$) and translation (synthesis of protein from $	ext{mRNA}$) occur in the same cellular compartment.Furthermore,bacterial $	ext{mRNA}$ does not require complex post-transcriptional processing (like splicing,capping,or tailing) to become active.As a result,translation can begin even before the transcription of the $	ext{mRNA}$ molecule is fully completed.This phenomenon is known as coupled transcription and translation.Therefore,both the Assertion and the Reason are true,and the Reason correctly explains the Assertion.

List $I$	List $II$
$A$. $RNA$ polymerase $III$	$I$. snRNPs
$B$. Termination of transcription	$II$. Promoter
$C$. Splicing of exons	$III$. Rho factor
$D$. $TATA$ box	$IV$. snRNAs,tRNA

Assertion: The transcription and translation can be coupled in bacteria.
Reason: In bacteria,since the $\text{mRNA}$ does not require any processing to become active,and also since transcription and translation take place in the same compartment.
