Question
Name the main stages of translation.
✓

Answer

The formation of a poly-peptide chain from mRNA is known as translation. The process of translation takes place on ribosome. The sequence of three nitrogen bases present in 5'-3' direction on m-RNA is called genetic code. This code determines the sequence of amino acids in a poly-peptide chain. Ribosome joins the m-RNA at 5' and when it moves towards 3', messages of DNA present as codon in m-RNA are translated.
The process of translation is completed in following steps :
1. Activation of Amino acids
2. Charging of t-RNA
3. Initiation
4. Elongation of polypeptide chain
5. Termination of polypeptide chain
