BLAST Bioinformatics

In this activity, students employ the same tools used by research scientists all over the world: online databases that allow comparison of DNA and protein sequences across species. Students compare 100-nucleotide sequences of the Hemoglobin B gene (HBB) to determine the relatedness of five different mammals. HBB codes for the beta chain of the hemoglobin protein; this chain is also referred to as beta globin.
