Number of cyclic tripeptides formed with 2 amino acids A and B is:
Show Hint
For cyclic peptides:
• Count unique sequences considering the cyclic structure to avoid duplicates.
• Use the number of amino acids and their combinations to determine possible arrangements.
- 3
4
2
- 5
The Correct Option is B
Solution and Explanation
1. Cyclic Tripeptides:
- A cyclic tripeptide is a peptide consisting of three amino acids arranged in a cyclic structure without any free ends.
- Given two amino acids, A and B, the tripeptide can have different arrangements depending on the sequence of A and B.
2. Possible Arrangements:
- The cyclic nature of the tripeptide eliminates linear sequence redundancy.
- The distinct arrangements are:
1. A-A-A
2. A-A-B
3. A-B-A
4. A-B-B
Total: 4 unique cyclic tripeptides.
