13: Epigenetics and Gender with Dr Karissa Sanbonmatsu

How can a single fertilized egg give rise to a complex organism with varied cells?  The answers may be found in epigenetics, the study of how cells control gene activity by reading, but not changing the DNA sequence. This episode explores the topic in language the layman can understand with our guest, Dr. Karissa Sanbonmatsu, a structural biologist working in epigenetics at the Los Alamos National Laboratory.
