$RNA$ synthesis is controlled by:

Give scientific reasons: Transcription and translation could be coupled in prokaryotic cell but not in eukaryotic cell.

Do you think that the alternate splicing of exons may enable a structural gene to code for several isoproteins from one and the same gene? If yes,how? If not,why so?

If the sequence of nitrogenous bases in $DNA$ is $ATTCGATG$,what will be the sequence of bases in the $mRNA$ transcript?

Given below are two statements, one is labelled Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A) :$ In eukaryotes, primary transcripts $(hnRNA)$ contain both exons and introns, and introns are non-functional.
Reason $(R) :$ In bacteria, the $mRNA$ does not require any processing, and transcription and translation take place in the same compartment.
In the light of the above statements, choose the most appropriate answer from the options given below $:$

Identify the incorrect statement.
