Which of the following is correct for $m-RNA$ in eukaryotes?

The $RNA$ polymerase $III$ is responsible for the transcription of which $RNA$?

Which of the following statements are correct?
$i. r-RNA$ provides the template for synthesis of proteins.
$ii. t-RNA$ brings amino acids and reads the genetic code.
$iii. RNA$ polymerase binds to promoter and initiates transcription.
$iv. A$ segment of $DNA$ coding for a polypeptide is called an intron.

Removal of $RNA$ polymerase $III$ from nucleoplasm will affect the synthesis of

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:

During transcription,the $DNA$ strand with $3' \rightarrow 5'$ polarity of the structural gene always acts as a template because
