Multiple Sequence Alignment Tool

Multiple Sequence Alignment (MSA) aligns three or more related biological sequences so you can inspect conserved positions, mismatches, gaps, and inferred homology more clearly.

Paste at least 3 sequences in FASTA format. This lightweight in-browser aligner is ideal for quick visual comparison of short to moderate-length sequences.
