Vedclass · Answer

(B) Option $B$ is correct. $rRNA$ (ribosomal $RNA$) acts as a structural and catalytic component of ribosomes and is characterized by complex secondary structures due to extensive folding.- Option $A$ is incorrect because $DNA$ strands are anti-parallel and complementary to each other.- Option $C$ is incorrect because both leading and lagging strands are synthesized in the $5' \rightarrow 3'$ direction by $DNA$ polymerase.- Option $D$ is incorrect because $mRNA$ is typically a linear molecule that carries the genetic code; it does not typically form hairpin structures like $tRNA$ or $rRNA$.

$B$. Polycistronic gene	$II$. Intervening sequence
$C$. Exons	$III$. Mostly prokaryotes
