This discovery proved an exception to the “central dogma” of genetic theory, which states that the information encoded in genes always flows unidirectionally from DNA to RNA (and thence to proteins) and cannot be reversed. Let us know if you have suggestions to improve this article (requires login). The discovery that the information in RNA can be transferred to DNA meant that the generally accepted rule that genetic information was only transferred in one direction - from DNA to RNA, to protein - had to be modified. He worked with Dulbecco at the Salk Institute in La Jolla, California (1965–68), studying the mechanism of replication of the poliovirus. David Baltimore The coauthor of the article, Thereza Imanishi-Kari, was accused of falsifying data published in the paper. In Boston, Baltimore and Huang, who had married, showed that VSV, an RNA virus, reproduced itself by means of an unusual enzyme (an RNA-dependent RNA polymerase) that copies RNA by a process not involving DNA.

Look for popular awards and laureates in different fields, and discover the history of the Nobel Prize. Baltimore became director of the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts, in 1983 and in 1990 left to become president of Rockefeller University. For more than a century, these academic institutions have worked independently to select Nobel Laureates in each prize category. Omissions? They simultaneously demonstrated that these RNA viruses, now called retroviruses, contain the blueprint for an unusual enzyme—a polymerase called reverse transcriptase—that copies DNA from an RNA template.

Baltimore received an undergraduate degree in chemistry from Swarthmore College, Pennsylvania (B.A., 1960), and went on to study animal virology at the Rockefeller Institute (now Rockefeller University) in New York City, where he obtained a doctorate in 1964, and at the Massachusetts Institute of Technology (MIT) in Boston. Twelve laureates were awarded a Nobel Prize in 2020, for achievements that have conferred the greatest benefit to humankind. …Satoshi Mizutani, and American virologist.

Because of his involvement in the case, however, he was asked to resign as president of Rockefeller University, and in 1994 he returned to MIT. Working independently, Baltimore and Temin discovered reverse transcriptase, an enzyme that synthesizes DNA from RNA.

Among his other appointments, he served as a member of the Encyclopædia Britannica Editorial Board of Advisors. Articles from Britannica Encyclopedias for elementary and high school students. Our editors will review what you’ve submitted and determine whether to revise the article. Sun. David Baltimore, (born March 7, 1938, New York, New York, U.S.), American virologist who shared the Nobel Prize for Physiology or Medicine in 1975 with Howard M. Temin and Renato Dulbecco. After Renato Dulbecco discovered that tumor viruses operate by incorporating their DNA into the DNA of host cells, David Baltimore and Howard Temin - independently of one another - discovered that viruses with genomes consisting of RNA can also be inserted into host cells' DNA. David Baltimore, American virologist who shared the 1975 Nobel Prize for Physiology or Medicine with Howard M. Temin and Renato Dulbecco. Such research contributed to an understanding of the … Several outreach organisations and activities have been developed to inspire generations and disseminate knowledge about the Nobel Prize. Baltimore joined the faculty of MIT in 1968, accompanied by Alice Huang, a postdoctoral fellow who had worked on vesicular stomatitus virus (VSV) at the Salk Institute.

In 1989 he figured prominently in a public dispute over a 1986 paper published in the journal Cell that he had coauthored while still at MIT. Baltimore and Temin both studied the process by which certain tumour-causing RNA viruses (those whose genetic material is composed of RNA) replicate after they infect a cell.

The newly formed viral DNA then integrates into the infected host cell, an event that can transform the infected cell into a cancer cell. Corrections? Working independently, Baltimore and Temin discovered reverse transcriptase. The Nobel Prize in Physiology or Medicine 1975 was awarded jointly to David Baltimore, Renato Dulbecco and Howard Martin Temin "for their discoveries concerning the interaction between tumour viruses and the genetic material of the cell". The Nobel Prize in Physiology or Medicine 1975, Born: 7 March 1938, New York, NY, USA, Affiliation at the time of the award: Massachusetts Institute of Technology (MIT), Cambridge, MA, USA, Prize motivation: "for their discoveries concerning the interaction between tumour viruses and the genetic material of the cell.". In 1996 a U.S. government panel cleared Imanishi-Kari of the charges of scientific misconduct. Baltimore then turned his attention to two RNA tumour viruses—Rauscher murine leukemia virus and Rous sarcoma virus—to discover whether a similar enzyme was at work in their replication. Since its discovery, reverse transcriptase has become an invaluable tool in recombinant DNA technology. 29 Nov 2020. Baltimore, who was not included in charges of misconduct, stood behind Imanishi-Kari, although he did retract the article. The research of all three men contributed to an understanding of the role of viruses in the development of cancer.
