Multiple Alignment Tool

The tool performs online multiple sequence alignment for DNA, RNA, or protein sequences, enabling researchers and students to compare several sequences and reveal conserved regions and potential functional motifs.
Conceptually, alignment uses a progressive strategy: a guide tree derived from pairwise distances informs the order of alignment; each step aligns two sequences or profiles using a scoring matrix and gap penalties; the result is a final multiple alignment with a defined length and column composition.
Core benefits include fast access without installation, reproducible parameter choices, and easy export to standard formats for downstream analysis or teaching; it supports both experimental and classroom workflows, letting users iterate with different matrices and gaps to compare outcomes.
Key differentiators are accessibility, support for batch handling, decision guidance via recommended defaults, and transparent algorithmic options; use cases include identifying conserved motifs, validating primer binding sites, annotating alignments for protein domains, and generating teaching examples.
