Amino acid sequence, in protein synthesis is decided by the sequence of
$rRNA$
$tRNA$
$mRNA$
$cDNA$
When a mature $mRNA$ was hybridised to its gene certain loops were observed. These loops represent
Define a cistron. Giving examples differentiate between monocistronic and polyeistronic transcription unit.
Which $RNA$ carries information from $DNA$ in protein synthesis
Give scientific reasons : Both the strands of $DNA$ are not copied during transcription.
In tailing, adenylate residues are added at $3'$ end
