(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
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’.
