What is the theoretical number of chemically different dipeptides that maybe assembled from two amino acids?
No. of dipeptides = 2n ; n = no. of amino acids i.e., 22 = 4 dipeptides can be formed.
How many dipeptides are possible from two molecules?
Two molecules of an α-amino acid will form only one dipeptide, the four different dipeptides are formed when two α-amino acids are different.
How many dipeptides are possible from two typical alpha amino acids?
Explanation: 4 different dipeptides are formed when 2 α−amino acids are different.
How many chemically different dipeptides can be formed from 20 amino acids?
4. Four is the theoretical number of chemically different dipeptides that may be assembled from two amino acids. Explanation: A dipeptide is an organic compound formed when a peptide bond joins two amino acids.
How many different dipeptides can be made using all 20 amino acids?
400
3. How many different dipeptides could be made with 20 types of amino acids? A dipeptide consists of two, linked amino acids: Twenty different amino acids are possible for position #1, and 20 different amino acids can be used in position #2. Thus, the total number of possibilities is 20 x 20 = 400.
How many different dipeptides may be assembled from 12 different amino acids?
What is the theoretical number of chemically different dipeptides that may be assembled from 12 different types of amino acids? the answer is C (144). The working is: 12^2 = 144. Here 12 is the no. of different amino acids and 2 is the no. of amino acids in the chain (its a dipeptide so, 2 amino acids).
How do you calculate the number of amino acids in a polypeptide?
X^Y (X to the power of Y). Where X is the number of different amino acids you will allow (2 or 10 in the specific question), and Y is the length of your polypeptide (dipeptide means only 2 long). You also need to define if you can re-use the amino acid, i.e. if the two amino acids can be the same.
How many ways in which second amino acid can be selected?
Dipeptide = two amino acids connected by amide linkage. Two amino acids can be selected out of these 20 amino acids without any restriction. Number of ways in which second amino acid can be chosen is again 20.
Why do some amino acids have multiple codons?
In fact most amino acids have multiple codons assigned to them, which makes your DNA more resistant to mutations through redundancy. Dipeptide = two amino acids connected by amide linkage. Two amino acids can be selected out of these 20 amino acids without any restriction.
