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

$RNA$ polymerase-$I$ is not responsible for the synthesis of $-$ (in $\text{s rRNA}$)

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.

$Statement A$: The primary transcript produced in eukaryotes is translated without undergoing any modification or processing.
$Statement B$: The $hnRNA$ in humans has exons and introns.

Select the appropriate option for the coding sequence (expressed sequence).

Where is the transcription unit found?
