Detailed explanation-1: -Answer and Explanation: tRNA read RNA nucleotides in a triplet. One codon corresponds to three nucleotides. One codon translates to one amino acid.
Detailed explanation-2: -Furthermore, if amino acids in all proteins coded in the human genome are boldly estimated to number 108, the combinatorial sets of seven amino acids in them, which is 108, is only one-tenth of the all possible combinatorial sets of seven amino acids, 1.3 × 109 ( = 207).
Detailed explanation-3: -The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid.
Detailed explanation-4: -For example, six codons specify leucine, serine, and arginine, and four codons specify glycine, valine, proline, threonine, and alanine. Eight amino acids have two codons, whereas there is one codon each for methionine and tryptophan.
