Detailed explanation-1: -(KOH-don) A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Certain codons signal the start or end of translation. These are called start or stop (or termination) codons.
Detailed explanation-2: -codon– a sequence of three nucleotides on a mRNA molecule that encode a specific amino acid. complementary-matching, such as between pairs of nucleotides in a DNA molecule.
Detailed explanation-3: -mRNA codons are read from 5’ to 3’, and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus. Translation involves reading the mRNA nucleotides in groups of three; each group specifies an amino acid (or provides a stop signal indicating that translation is finished).
