Web tools for the alignment of multiple biological sequences (protein or nucleic acid). From the output, homology can be inferred. Visual depictions of the alignment can illustrate events such as point mutations, insertions, deletions, etc. Useful in assessing conservation of domains, tertiary/secondary structures, residues or nucleotides.
Web tool for finding regions of similarity between biological sequences; nucleotide/protein, various genomes, complex queries. Useful in identifying any sequences that resemble query sequence.
