Chapter 7, Problem 9MCQ
Summary Introduction
Introduction:
Amino acids are the organic compounds that serve as building block for protein. It consists of amino group and carboxylic group that are joined together by a peptide bond. Each amino acid is coded by a specific codon. Codon is the sequence of DNA or RNA that codes for amino acids and involve in initiation and termination of protein synthesis.
