Question:
Which of the following is NOT a multiple sequence alignment program?
Which of the following is NOT a multiple sequence alignment program?
Show Hint
• CLUSTAL family + PILEUP → Alignment tools
• AMBER → Molecular dynamics, not alignment
Updated On: May 13, 2026
- CLUSTALX
- AMBER
- CLUSTALW
- PILEUP
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Multiple Sequence Alignment (MSA) programs are used to align three or more biological sequences (DNA, RNA, or protein) to identify similarities and evolutionary relationships.
• Common MSA tools include CLUSTALX, CLUSTALW, and PILEUP.
• Some software tools serve different purposes like molecular dynamics simulations.
Step 1: Analyzing each option.
• CLUSTALX: A widely used graphical interface for multiple sequence alignment → MSA program.
• AMBER: A molecular dynamics simulation software used for biomolecular modeling → Not an MSA program.
• CLUSTALW: A widely used multiple sequence alignment tool → MSA program.
• PILEUP: A program used for sequence alignment → MSA program.
Step 2: Identifying the correct answer.
Only AMBER is not a multiple sequence alignment program.
• Common MSA tools include CLUSTALX, CLUSTALW, and PILEUP.
