(N/A) Repetitive $DNA$ and Satellite $DNA$

Repetitive $DNA$	Satellite $DNA$
$DNA$ sequences that contain small segments repeated many times in the genome.	$A$ subset of repetitive $DNA$ consisting of highly repetitive sequences that form distinct bands during density gradient centrifugation.

$(b)$ $mRNA$ and $tRNA$

No.	$mRNA$ (Messenger $RNA$)	$tRNA$ (Transfer $RNA$)
$1.$	Acts as a template that carries genetic information from $DNA$ for protein synthesis.	Acts as an adaptor molecule that carries specific amino acids to the ribosome during translation.
$2.$	It is a linear molecule.	It has a characteristic clover-leaf secondary structure (or $L$-shape $3D$ structure).

$(c)$ Template strand and Coding strand

No.	Template Strand	Coding Strand
$1.$	Acts as a template for $RNA$ synthesis; its sequence is complementary to the $mRNA$.	Does not act as a template; its sequence is identical to the $mRNA$ (except $U$ replaces $T$).
$2.$	It runs in the $3' \to 5'$ direction.	It runs in the $5' \to 3'$ direction.

List-$I$	List-$II$
$A$. Monocistronic gene	$I$. Coding sequence
$B$. Polycistronic gene	$II$. Intervening sequence
$C$. Exons	$III$. Mostly prokaryotes
$D$. Introns	$IV$. Mostly eukaryotes

Differentiate between the following:
$(a)$ Repetitive $DNA$ and Satellite $DNA$
$(b)$ $mRNA$ and $tRNA$
$(c)$ Template strand and Coding strand
