There are 20 naturally occurring amino acids. The maximum number of tripeptides that can be obtained are

Dear Student,

Please find below the solution to the asked query.

The correct answer is 8000.

Use the formula n^r to calculate the number.
where n = number of amino acids = 20
r = length of chain 

Here, r = 3 as we have to make tripeptide.

So, maximum number of tripeptides formed from 20 natural amino acids = 20³ = 8000
