Vedclass · Answer

(A) For a tripeptide,there are $3$ positions to be filled by either valine $(V)$ or proline $(P)$.Since each position can be occupied by either of the $2$ amino acids,the total number of possible combinations is $2^n$,where $n$ is the number of amino acids in the peptide.For a tripeptide,$n = 3$,so the total number of combinations is $2^3 = 8$.The possible combinations are:$1$. $Val-Val-Val$$2$. $Pro-Pro-Pro$$3$. $Val-Pro-Pro$$4$. $Pro-Val-Pro$$5$. $Val-Val-Pro$$6$. $Val-Pro-Val$$7$. $Pro-Pro-Val$$8$. $Pro-Val-Val$

Total number of tripeptides possible by mixing of valine and proline is $............$.
