Answer:

Dipeptide = two amino acids connected by amide linkage.

Two amino acids can be selected out of these 20 amino acids without any restriction.

The number of ways first amino acid can be chose out of 20 = 20

Number of ways in which second amino acid can be chosen is again 20.

Total number of chosing randomly to make a dipeptide= 20x20=400

If question was that you are given only these 20 amino acid molecules (i.e. You have just 20 different molecules) and you have to make dipeptide out of these available amino acids then…

Ways for chosing first amino acid= 20 (as any one out of 20 can be taken)

then number of ways to select second= 19 (as one less is there now due to above selection)

Total number of ways now= 20x19= 380

Answer:

The correct answer to this question is Two connected amino acids make up a dipeptide. Position #1 can utilize 20 different amino acids, and position #2 can use 20 different amino acids.

Explanation:

Given -  The theoretical number of chemically different dipeptides.

To Find  - What is the theoretical number of chemically different dipeptides that may be assembled from 12 different types of amino acids?

Two connected amino acids make up a dipeptide. Position #1 can utilize 20 different amino acids, and position #2 can use 20 different amino acids. Thus, there are 20 x 20 = 400 possible outcomes. Only one dipeptide can be created by two molecules of an "alpha" amino acid; the four distinct dipeptides are created when there are two different "alpha" amino acids.

Dipeptides may be created from 22 amino acids, which equals 2n dipeptides.
