Monica Smith (left) and Ashley Estes, both students at Cleveland NJROTC School at Pruitt, learn from Jacqui Hawkins, a second-year medical student, how to extract DNA from a strawberry using shampoo and alcohol. The high-school students were at the School of Medicine Nov. 7 for Women in Science Day, which brings young women from St. Louis Public Schools to Washington University for hands-on activities, speakers, tours of facilities and career advice. The University hosted 100 high-school women for the day, sponsored by the Young Scientists Program and Association for Women in Science-St. Louis.
