Question

Quizplus · Accepted Answer

A tripeptide consists of three amino acids linked together. Since there are three different amino acids (tyrosine, valine, and alanine) and each position in the tripeptide can be occupied by any of the three amino acids without repetition, the number of different tripeptides that can be formed is calculated by permutations: 3! = 3 × 2 × 1 = 6.
