The BLAST Tutorial

This tutorial is designed as a quick introduction to the BLAST family of sequence analysis programs.

These slides show a progression of steps in using blastn, beginning at the home page for the National Center for Biotechnology Information (NCBI) ( and ending at PubMed, a tool for searching scientific literature. In this series, you will see how to submit a nucleotide sequence, compare it to other sequences using blastn, and interpret some of the results. Visit the Tutorial.
