DNA sequence alignment viewed with the multiple alignment editor Se-Al. On the far right there are insertions and/or deletions in several sequences (click pic for full-size image)We a small and crude (quick and dirty?) overview of some of the few tools available to work in bioinformatics.
The main focus of our exercise was the use of the algorithm known as BLAST (Basic Local Alignment Search Tool), available at the NCBI webpage. After an overview of some of the main features of the site, we "BLASTed" (used BLAST) a few unknown protein (using 'protein BLAST') and nucleotide (using 'nucleotide BLAST') sequences. We found out what the sequences were and to what organisms they belonged. This is one of many possible uses of the BLAST algorithm.
