Detailed explanation-1: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
Detailed explanation-2: -DNA? provides instructions for making proteins? (as explained by the central dogma?). The sequence of the bases?, A, C, G and T, in DNA determines our unique genetic code and provides the instructions for producing molecules in the body. The cell reads the DNA code in groups of three bases.
Detailed explanation-3: -Groups of three bases form codons, and each codon stands for one amino acid (or start or stop). The codons are read in sequence following the start codon until a stop codon is reached. The genetic code is universal, unambiguous, and redundant.
Detailed explanation-4: -A coding DNA sequence encodes protein by encoding each amino acid of the protein into a triplet of nucleotides, also called a codon.
