The first video is a shortened version in which Dr. David Baltimore introduces the different types of viruses, and defines how viruses are classified depending on their genetic material. Using HIV as an example, Baltimore explains what constitutes an equilibrium versus a non-equilibrium virus, and shows how the discovery of the reverse transcriptase helped scientist understand viruses.
The second video is an extended edition in which Baltimore also outlines the sequence of events that led to the Nobel Prize-winning discovery of reverse transcriptase, an enzyme that converts a sequence in an RNA molecule into a sequence in a DNA molecule. As Baltimore explains, the discovery of reverse transcriptase has revolutionized modern molecular biology, and it has aided in the understanding of viruses like HIV, and the genetic basis of cancer.
After serving as President of the California Institute of Technology for nine years, in 2006 David Baltimore was appointed President Emeritus and the Robert Andrews Millikan Professor of Biology. Born in New York City, he received his B.A. in Chemistry from Swarthmore College in 1960 and a Ph.D. in 1964 from Rockefeller University, where he… Continue Reading
