Explain the process of elongation during translation.
Expert Solution
Step 1: Introduction
Protein is a polypeptide molecule composed of amino acids linked together by peptide bonds. It is synthesized by the translation of mRNA in the ribosome. Genetic information stored in the DNA molecule will be transcribed into mRNA which is then transported to the ribosome for translation.
Translation comprises initiation, elongation, and termination. In the ribosome, the mRNA sequence will read as codon and tRNA will add an amino acid complementary to the codon. Protein translation will begin with the recognition of the start codon and the addition of initial amino acid (methionine in eukaryotes and formyl-methionine in prokaryotes).
