(a) Repetitive DNA and satellite DNA
| satellite DNA Repetitive DNA |
Satellite DNA |
| 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 |
| 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. |
| It is a linear molecule |
It has clover leaf shape. |
(c) Template strand and coding
| Template strand |
Coding strand |
| Template strand of DNS act 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) |
| It runs from 3" to 5" |
It runs from 5" to 3" |
