DNA contains four types of nucleotides which can be arranged in numerous ways. This arrangement of nucleotides is basically a coded language connected with the protein synthesis which tells about the sequence of amino acids in a polypeptide chain. It was hypothesized that the triplet sequence of nucleotides codon codes for one amino acid. Therefore the number of possible codons can be 64 whereas the number of amino acids is 20. Nirenberg and Matthaei worked on the degeneracy of codons that is which codon codes for which amino acid. So take this quiz and increase your knowledge about genetic code.
