“The next step is bringing the samples into a lab for DNA extraction. I do this at Genspace, a DIY Biology lab in downtown Brooklyn, or when I am upstate at school I do it in the student Molecular Biology lab there.

I extract the DNA in the lab and then I amplify certain regions of it using a technique called PCR – Polymerase Chain Reaction. This allows me to study certain regions of the genome that tend to vary person to person, what are called SNPs or Single Nucleotide Polymorphisms.”
