1.
|
The process involving the synthesis of m-RNA from DNA is called transcription.
|
The process involving the decoding of the sequence of nucleotides (Codons) present in the m-RNA into the sequence of a polypeptide chain is called translation.
|
|
2.
|
It takes place in the nucleus.
|
It takes place in the cytoplasm.
|
|
3.
|
m-RNA is synthesized by using one of the DNA strands as the template.
|
Codons present on m-RNA act as templates for the synthesis of proteins.
|
|
4.
|
It occurs in presence of the enzyme RNA Polymerase.
|
It occurs in presence of the enzyme Aminoacyl t-RNA synthetase.
|
|
5.
|
It does not require the participation of
t-RNA, r-RNA, ribosomes and non-sense codons.
|
It requires the participation of
t-RNA, r-RNA, ribosomes and non-sense codons.
|
|
6.
|
In eukaryotes, the m-RNA formed undergoes post-transcriptional modification such as 5’ capping, 3’ Poly-A tail, splicing of introns.
|
The protein formed after translation undergo post-translation modifications like phosphorylation, methylation, glycosylation, sulphonation, etc.
