David Baltimore David Baltimore nel 2013 Premio Nobel per la medicina 1975 David Baltimore ( New York, 7 marzo 1938) è un biologo statunitense, amministratore universitario e vincitore del Premio Nobel.

David Baltimore, född 7 mars 1938 i New York City, är en amerikansk mikrobiolog och nobelpristagare. År 1975 erhöll han Nobelpriset i fysiologi eller medicin tillsammans med Renato Dulbecco och Howard M. Temin. Han är professor i biologi vid California Institute of Technology (Caltech), där han tjänstgjorde som president från 1997 till 2006.

Baltimore entdeckte unabhängig von Temin das Enzym Reverse Transkriptase, das die Ribonukleinsäure (RNA) in Desoxyribonukleinsäure (DNA) umschreibt. RNA und DNA spielen eine wichtige Rolle in der Synthese von Proteinen und der Weitergabe des Erbguts.

20-12-2011 · He found that reverse transcriptase can copy RNA into DNA, indicating that some viruses replicate via a DNA intermediate. The finding, which won Baltimore and others the 1975 Nobel Prize in Physiology or Medicine, enriched biologists’ views on the direction of flow of genetic information in cells.

24-10-2022 · In 1970, David Baltimore — discovered reverse transcription, the process by which retroviruses infiltrate healthy cells and use the host’s cellular machinery to replicate. For this discovery and his subsequent work with reverse transcriptases, Dr. Baltimore received a share of the 1975 Nobel Prize in Physiology or Medicine.

David Baltimore (1938– ) [1] By: Zhu, Meilin David Baltimore studied viruses and the immune system in the US during the twentieth century. In 1975, Baltimore was awarded the Nobel Prize in Physiology or Medicine for discovering reverse transcriptase, the enzyme used to transfer information from RNA to DNA.

This process is known as reverse transcription and is catalyzed by the enzyme reverse transcriptase . Its implications had a great effect on the study of cancerand the role of viruses in causing the disease. Born March 7, 1938, in New York City to Richard Baltimore and Gertrude Lipschitz, David was a gifted student of science.

Temin accumulated certain indirect evidences supporting his theory but the major breakthrough occurred in 1970 when simultaneously Temin and also David Baltimore showed the occurrence of a specific enzyme in RNA tumour virus particles which could make a DNA copy from RNA. This enzyme was called reverse transcriptase.

However, in 1970 when Mizutani and Howard Temin at Madison and David Baltimore at MIT, USA discovered the enzyme responsible for reverse transcription, named reverse transcriptase, the possibility that genetic information could be passed on in the reverse manner was finally accepted (Fig. 13.13).
