His work on genetic recombination propelled the field of molecular genetics to the forefront. He shared the 1958 Nobel Prize for physiology or medicine with two associates. ”.

This process is called transduction. 1 Joshua Lederberg Joshua Lederberg (1925-2 February 2008) was one of the pioneers of molecular genetics perhaps best known for his discovery of genetic recombination in bacteria (Lederberg and Tatum 1946) which earned him a Nobel Prize in 1958 (shared with George Beadle and Edward Tatum).

It was first discovered by Joshua Lederberg in 1952. The "blender" experiment proved that DNA carried genetic information. In this experiment, they capitalized on the ease with which bacteria can be grown and maintained. Transduction is the process by which bacterial DNA is moved from one bacterium to another by a virus.

While DNA had been known to biologists since 1869, many scientists still assumed at the time that proteins carried the information for inheritance because DNA appeared to be an inert molecule, and, since it is located in the nucleus, its role was considered to be phosphorus storage.

Lee Ligon, PhD In 1958, the Nobel Prize in Physiology or Medicine went to a young man of 33 years of age for his discovery that bacteria reproduce by the mutual exchange of genes and that some viruses carry hereditary materials from one bacterial … the dramatic assertion, from the suitably scientific and imposing "Joshua Lederberg, Ph.D., Nobel Laureate," that "The single biggest threat to man's continued domi nation of the planet is the virus."
