Blast Windows, Mac, Linux
By National Center for Biotechnology Information
For Everybody

The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.

Clustal Omega Windows, Mac, Linux
Clustal Omega
By The European Bioinformatics Institute
For Everybody

Clustal is a general purpose multiple sequence alignment program for DNA or proteins.It produces biologically meaningful multiple sequence alignments of divergent sequences. It calculates the best match for the selected sequences, and lines them up so that the identities, similarities and differences can be seen. Evolutionary relationships can be seen via viewing Cladograms or Phylograms.

Clustal W/Clustal X ("Classic Clustal") is no longer supported, but is still available for download at the Clustal website.
