The DNA obsession
Description
One of the most important stories in genetics is the race to understand DNA. This intro-level program guides viewers through that story, focusing on the biological and chemical processes central to the transfer of genetic material. Beginning in the middle of the 19th century, the program describes how competing scientists in Europe and America zeroed in on the DNA molecule and determined its structure. Friedrich Miescher's identification of "nuclein," Frederick Griffith's pneumococcus studies, Joshua Lederberg's analysis of bacteria reproduction, and James Watson and Francis Crick's double-helix configuration highlight the obsession, rivalry, and collaboration that drive scientific discovery.
