The informational part of i-RNA contains 135 nucleotides. Determine the number of amino acids included in the protein

The informational part of i-RNA contains 135 nucleotides. Determine the number of amino acids included in the protein it encodes, the number of t-RNA molecules involved in the biosynthesis of this protein, the number of triplets in the gene region that encode the primary structure of this protein. Explain the results obtained.

1) the amino acid is encoded by a triplet of nucleotides, therefore, the protein contains 135: 3 = 45 amino acids;
2) since t-RNA transports one amino acid, 45 t-RNA was needed for translation (assembly of a protein molecule);
3) i-RNA is a copy of the gene encoding this protein, therefore the gene contains 135: 3 = 45 triplets.
