Define the following terms: $Cistron$ and $Terminator$.

Messenger $RNA$ $(mRNA)$ is produced in:

If the template strand of $DNA$ is $3'-CTGATAGC-5'$,what will be the sequence of the transcribed $RNA$?

Which of the following statements are correct with reference to a transcription unit?
$A$. $A$ transcription unit in $DNA$ is defined primarily by three regions: promoter, structural gene and terminator.
$B$. The promoter is said to be located towards the $5'$-end of the structural gene.
$C$. The promoter is a $DNA$ sequence that provides binding site for $RNA$ polymerase.
$D$. The promoter defines the template and coding strands.
$E$. The terminator is located towards the $3'$-end of the coding strand and it defines the end of the process of transcription.
Choose the correct answer from the options given below:

$DNA$-dependent $RNA$ polymerase catalyses transcription on one strand of the $DNA$ which is called the

$(a)$ $A$ is the Coding strand
$(b)$ $A$ is the Non-coding strand
$(c)$ $B$ is the Antisense strand
$(d)$ $B$ is the Sense strand
