Question 1 Report
| Triplet 1 | Triplet 2 | Triplet 3 |
|---|---|---|
| CAT | GGA | TTC |
The table shows part of a gene divided into base triplets, each coding for one amino acid. How many amino acids are coded for by the section shown?
The bases of a gene are read in triplets, and each triplet codes for one amino acid. The section shown contains three triplets (CAT, GGA and TTC), so it codes for 3 amino acids. Counting the triplets, not the individual bases, gives the number of amino acids; the nine individual bases here make up exactly three triplets, so the answer is three amino acids.
