Formation of protein from RNA is known as translation. This mechanism is divided into following steps-
1. Activation of amino acids
2. Initiation
3. Elongation
4. Termination
Amino acids are activated by t-RNA. These activated amino acids binds with m-RNA. AUG is initiating codon because it initiates translation. Ribosome covers whole complex (amino acid t-RNA m-RNA complex). Many amino acids enter in this complex and formed polypeptide chain. When releasing factor enters in this, it releases protein (polypeptide chain) from complex.
