Multi-Sequence Alignment | Momchi's Genetics Tools™

Multi-Sequence Alignment (up to 4 sequences)

Paste sequences (FASTA or raw). Choose DNA / Protein mode. Uses global Needleman–Wunsch and a simple progressive (star/profile) strategy to align up to 4 sequences in-browser.

Sequence 1

Sequence 2

Sequence 3 (optional)

Sequence 4 (optional)

Mode: Match: Mismatch: Gap penalty:

No alignment yet.

This tool performs multiple sequence alignment (MSA) of up to four DNA or protein sequences using the Needleman–Wunsch algorithm. It displays color-coded alignments, a consensus sequence, and conservation levels to help users visually compare similarities and differences between sequences.
