May is AP exam and end-of-school-year activities for high schoolers in New York City and elsewhere, but that didn't stop about 25 girls interested in STEM careers from attending RockEDU's PCR Lab Experience on May 14. The girls attend the East Side Community High School in Manhattan. They participated in hands-on demos at Rockefeller University's state-of-the-art outreach labs, around lab methods for isolating DNA. Expert scientists from the outreach lab led discussions around the ethics of DNA testing. Huntington's disease was used as an example and the girls got to practice gel electrophoresis with Huntington's model gel. A very exciting program, at a busy time of year for high school students!
