Question

How many distinct tetra peptides cane made from the two amino acids leucine and histidine? (each amino acid maybe used more than once)

Answer 1

Answer – In this one we are given the tetra peptides cane made from the two amino acids leucine and histidine and we need to determine the how many distinct tetra peptides cane made.

We know the formula for the determine the how many distinct cane made and it is as follow –

n^r

where n = number of amino acids are available and r is the number of chain, means length of chain.

We are given the two amino acid, so, n = 2 and length of chain is r = 4, since tetra peptides, so the number of distinct tetra peptides cane made from the two amino acids leucine and histidine as follow

= 2⁴

= 16
