Which of the following statements are correct with reference to the prokaryotic genome?
$A$. Monocistronic structural genes
$B$. Introns absent in structural genes
$C$. Transcription and translation are coupled processes
$D$. Primary transcript undergoes splicing
$E$. Only one $RNA$ polymerase is present

$RNA$ synthesis is controlled by:

During transcription,the $DNA$ strand which acts as a template is called $A$ strand and it has $B$ polarity.

The $TATA$ box of a eukaryotic promoter lies:
