Lesson Two: DNA Barcoding and the Barcode of Life Database (BOLD)

In this lesson, students will receive an “unknown” DNA sequence and use the bioinformatics tool Basic Local Alignment Search Tool (BLAST) to identify the species from which the sequence came. Students then visit the Barcode of Life Database (BOLD) to obtain taxonomic information about their species and form taxonomic groups for scientific collaboration. The lesson ends with each student generating a hypothesis about the relatedness of the species within each group. In Lesson Two, students learn how postdoctoral scientists in DNA and history might use bioinformatics tools in their career.
