Lecture Title: Do People Really Know What DNA Is?
April 26, 2024 - Biologists know what DNA is, although they’ll be the first to tell you there’s a lot about DNA they don’t know. But what does DNA mean to someone who is not a biologist? Even a scientifically literate person might have trouble explaining what DNA does, how it works, or what the discovery of its structure was so important to modern biology. How much does someone need to know about DNA to make informed decisions about genetic engineering, genetic privacy, or when life begins? Joe Palca, Ph.D., former science correspondent for National Public Radio (NPR) examines these questions in this talk, but as you will see these questions are not always so easy to answer. That’s what makes this work so interesting!
About the Louise M. Slaughter Lecture: Each year the National Human Genome Research Institute (NHGRI) honors the life and legacy of genomics champion Representative Louise M. Slaughter (D-N.Y.) - who passed away in March 2018 - by naming an annual National DNA Day lecture at the National Institutes of Health (NIH) in her honor. These lectures are intended to spark curiosity in NIH staff about how to engage with the public on DNA and its applications in society.

![NHGRIs Oral History Collection: Interview with Sarah Tishkoff
Sarah Tishkoff, Ph.D., is the David and Lyn Silfen Professor in the Department of Biology and Genetics at the University of Pennsylvania. Dr. Tishkoff is a recipient of the National Institutes of Health Director’s Pioneer Award, and she was elected to the National Academy of Sciences in 2017. She is a leading expert in researching human genetic diversity in African populations. In this oral history interview, recorded in 2016, Dr. Tishkoff recounts her early work in anthropology with Allan Wilson at the University of California, Berkeley. She also discusses in depth her groundbreaking work in studying human genetic variation across Africa.
The National Human Genome Research Institute’s (NHGRI) Oral History Collection features discussions with influential figures in the field of genomics and the history of institute. Intended for researchers and scholars, each oral history contains extensive conversation about science and medicine, biographical details and insights into the inner workings of institutions and initiatives.
