Transcription is a process by which
A transcription unit in $DNA$ is defined primarily by the three regions in $DNA$ and these are with respect to upstream and down stream end;
In capping .......... is added to the $5'$ end of hn $RNA$
$A$ : $5\;S rRNA$ and surrounding protein complex provides binding site of $tRNA$.
$R$ : $tRNA$ is soluble $RNA$ with unusual bases
Define a cistron. Giving examples differentiate between monocistronic and polyeistronic transcription unit.
