Learn about the role of mitochondrial DNA in human ancestry. First, students isolate their cheek cell DNA using a saline mouthwash. After PCR amplification of their mitochondrial control region, students set up cycle sequencing reactions for their mitochondrial control region. The subsequent sequencing procedures are done at California State University East Bay. Students learn how to analyze sequence data using single nucleotide polymorphisms (SNPs), and they determine their DNA haplogroup. They can upload their results to National Geographic’s Genographic Project and fine out which branch of the human family tree they belong to.
