DNA encodes genetic information through sequences of nucleotides, specifically four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G) [1][3]. The order of these bases forms genes, which provide instructions for protein synthesis [5][1]. Each gene comprises triplet codes, or codons, that specify amino acids, enabling the production of proteins essential for cellular functions [2][6]. This coding system is fundamental for inherited traits and the biochemical processes within organisms [4][1].
