Detailed explanation-1: -codon– a sequence of three nucleotides on a mRNA molecule that encode a specific amino acid. Anticodons are found on molecules of tRNA. Note:Each three-letter sequence of mRNA nucleotides (codons) corresponds to a specific amino acid, or to a stop codon.
Detailed explanation-2: -Codons in an mRNA are read during translation, beginning with a start codon and continuing until a stop codon is reached. 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.
Detailed explanation-3: -This order is determined by the attraction between a codon, a sequence of three nucleotides on the mRNA, and a complementary nucleotide triplet on the tRNA, called an anticodon.
