 | | Howard Martin Temin (1934-1994), American virologist and winner of the 1975 Nobel Prize in physiology or medicine, which he shared with American molecular biologist David Baltimore and Italian American virologist Renato Dulbecco for their discoveries concerning the action of viruses on the genetic structure of the cells they infect. |
 | | However, in 1965, while studying the Rous sarcoma virus, Temin discovered that RNA changed the DNA of the host cell by inserting its own genes. |
 | | Temin was derided by his peers for his outlandish proposal but held to the idea of “reverse transcription.” In 1970, working with Satoshi Mitzutani, Temin found an RNA viral enzyme, which he called RNA-directed DNA polymerase, that copies genetic information to the host cell's DNA. |
