Mention the steps of translation.

Solution

Translation. During translation process, proteins are made by the ribosomes on mRNA strand.
The main steps are:
1. Activation of amino acid.
2. Transfer of activated amino acid to tRNA.
3. Initiation of synthesis when the ribosome binds to the mRNA at the start codon (AUG).
4. Elongation of polypeptide chain. in which the tRNA and amino acid complex bind to the codon in mRNA by forming complementary base pairs with the tRNA anticodon. Ribosome moves from codon to codon and amino acids are added one by one.
5. Termination of chain- when the release factor binds to termination codon releasing the complete releasing polypeptide.
