Abstract
The nucleus of the cell contains the structural information for all proteins present in the cell, and is responsible directly or indirectly for the synthesis of all molecules in the cell. The information is coded in deoxyribonucleic acid (DNA) by the sequence of four nitrogenous bases: the purines adenine and guanine (A and G), and the pyrimidines cytosine and thymine (C and T). The information is carried in the form of a three letter code, the letters being A, G, C and T. Different arrangements of three consecutive bases code for different amino acids in the peptides to be synthesized. Such coding triplets are called codons. The segment of DNA that codes for one peptide chain is called a gene. Peptides are strings of amino acids that form the building blocks of enzymes and other proteins. There are 20 naturally occurring amino acids.
