Process of protein biosynthesis
There are signal sequences before the real coding sequence at the translation initiation sites. Amino acid activation is catalyzed by amino acyl-tRNA synthetase and couples it to its corresponding tRNA. Anti codon in tRNA molecule forms base pairs with the appropriate codon on the mRNA. In the initiation step, initiation factors are involved. Initiation factor is the protein that promotes the proper association of ribosomes with messenger RNA. In the elongation step, incorporation of an amino acid into a protein takes place. As a result, polypeptide chain is grown. Termination is the last stage in protein biosynthesis.
This activity will help students understand the role of DNA, mRNA, tRNA, and amino acids in protein synthesis. This activity will also introduce the concept of mutations.

is the beginning of protein synthesis and involves assembly of the ribosome, the tRNA that recognizes the start codon, and the mRNA molecule itself, as well as other accessory proteins.
