Differentiate between the followings:
$(a)$ Repetitive $DNA$ and Satellite $DNA$
$(b)$ $mRNA$ and $tRNA$
$(c)$ Template strand and Coding strand
$(a)$ Repetitive $DNA$ and satellite $DNA$
| Repetitive $DNA$ | satellite $DNA$ | |
| $1.$ Repetitive $DNA$ are $DNA$ sequences that contain small segments, which are repeated many times. | Satellite $DNA$ are $DNA$ sequences that contain highly repetitive $DNA$. | |
$(b)$ $mRNA$ and $tRNA$
| $mRNA$ | $tRNA$ | |
| $1.$ | $mRNA$ $tRNA$ $1.$ $mRNA$ or messenger $RNA$ acts as a template for the process of transcription. | $tRNA$ or transfer $RNA$ acts as an adaptor molecule that carries a specific amino acid to $mRNA$ for the synthesis of polypeptide. |
| $2.$ | It is a linear molecule. | It has clover leaf shape. |
$(c)$ Template strand and coding strand
| Template strand | coding strand | |
| $1.$ | Template strand of $DNA$ acts as a template for the synthesis of $mRNA$ during transcription. | Coding strand is a sequence of $DNA$ that has the same base sequence as that of $mRNA$ (except thymine that is replaced by uracil in $DNA$). |
| $2.$ | It runs from $3 '$ to $5 '$. | It runs from $5 '$ to $3 '$. |
