Franklin had died of ovarian cancer in Wilkins did mention her in passing. Watson went on to work with many others throughout the s. His genius appears to be his ability to coordinate the work of different individuals and combine their results into new conclusions. Inhe used a rotating anode X-ray to demonstrate the helical construction of the tobacco mosaic virus.

From tohe worked with scientists at the California Institute of Technology to build a plausible model of RNA structure. From tohe again worked with Crick on discovering principals of virus construction. Inhe moved to Harvard where he worked on RNA and protein synthesis. In the book, Watson used derogatory comments and rancorous personal descriptions of many people involved in the discovery, especially Franklin.

Because of this, Harvard Press refused to print the book. However, it was commercially published and was a great success. In a later edition, Watson excused his treatment of Franklin by stating that he had been unaware of the pressures she faced as a woman doing scientific research in the s. At the time, the institution was struggling financially, but Watson proved to be very good at raising funds for research.

He used his fund-raising acumen to pilot the project through until He resigned over a conflict about patenting genetic information. Watson believed any commercial patents would only hinder the pure research being done by scientists working on the project. His tenure at Cold Harbor ended abruptly. In Watson successfully completed his doctoral research project on the effect of x-rays upon the multiplication of bacteriophages viruses that attack bacterial cells.

Watson spent as a National Research Council fellow in Copenhagen doing postdoctoral work with biochemist Herman Kalckar. He had hoped to learn more about the biochemistry of the genetic material deoxyribonucleic acid DNA. Watson's next research post at Cavendish Laboratory, Cambridge, England, brought him into contact with the physicist turned biologist Francis Crick.

Together they shared an interest in DNA while he was preparing for his doctorate. Thus began the partnership between Watson and Crick which resulted in their joint proposal of the double-helical model of the DNA in That same year he published The Double Helix, revealing the human story behind the discovery of the DNA structure, including the rivalries and deceits which were practiced by all.

While at Harvard Watson wrote The Molecular Biology of the Genethe first widely used university textbook on molecular biology. This text has gone through seven editions and exists in two large volumes as a comprehensive treatise of the field. Less than two years later, inhe resigned in protest over policy differences in the operation of this massive project.

Watson, as his book The Double Helix confirms, has never avoided controversy. Nevertheless, his scientific brilliance is attested to by Crick, Delbruck, Luria, and others. The importance of his role in the DNA discovery has been well supported by Gunther Stent, a member of the Delbruck phage group, in an essay which discounts many of Watson's critics through well-reasoned arguments.

His work there has primarily been to facilitate and encourage the research of other scientists. James Watson is one of the most famous scientists of the twentieth century. He is recognized as a co-discoverer of the structure of deoxyribonucleic acid DNA and was a co-recipient of the Nobel Prize in medicine for his work in genetics.

James d. watson what he invented

Watson was born in ChicagoIllinois. He was an extremely intelligent child and used his photographic memory to his advantage. By age ten he was a regular contestant on a popular radio show called The Quiz Kids. He studied zoology at the University of Chicago when he was only 15 years old. By age 19 he was conducting research on viruses at the University of Indianawhere he earned his doctoral degree.

He continued his virus work in Denmark for a short period of time before several scientists convinced him to concentrate on genetics and molecular biology. This new direction led him to Cavendish Laboratory at Cambridge University in It was here that he first met Francis Harry Compton Crick A friendship soon developed between Watson and Crick.

It didn't take long before Watson's enthusiastic approach to genetic research persuaded Crick to assist him in developing a DNA model. During this time DNA research was not a high priority for most scientists. Watson and Crick entered the race to find the structure of DNA rather late. With the odds stacked against them, Watson and Crick proceeded to develop their own hypothesis.

They believed the DNA structure was actually made of two parallel strands. They obtained structural working models and attempted to fit the pieces together using proven chemical laws and prior studies. Many times the model, which resembled a large tinker-toy ladder, fell apart or simply did not fit previously established evidence. The researchers tedious task was somewhat like trying to put together a model airplane with only a small portion of the instruction sheet and no picture of how the assembled plane should look.

Finally, two major clues fell into place. Watson and Crick knew that the amounts of the base pairs of amino acids protein elements which connect the two strands of the DNA molecule, were about the same size and shape. Information supplied by Maurice Wilkins and Rosalind Elsie Franklin also suggested that the sugar-phosphate part of the structure was on the outside of the model.

Watson noticed that the base pairs fit neatly into the overall twisted ladder or double helix form without any distortion. It also meant that each side of the ladder fit into the other. This explained how DNA could be precisely copied each time a cell divides. The completed model consisted of a double backbone of sugar and phosphate molecules arranged in repeating units.

Between these, like rungs in a ladder, were the flat pairs of bases. In when Watson was only 25 years old, he and Crick announced their discovery. Almost ten years later, after numerous tests confirmed their results, the research team shared the Nobel Prize with Maurice Wilkins. Today we know that DNA is the molecule that contains the essential set of directions that each cell needs to perform vital life functions.

The details of the DNA molecule are so precise that differences in the microscopic structure could mean the difference between a man and a mouse, or between life and death. Since the DNA discovery Watson has published numerous papers, written several genetics textbooks, and taught at the California Institute of Technology and Harvard University.

Watson divides his time between two demanding administrative positions. He is director of the prestigious Cold Spring Harbor Laboratory in New York an institution involved in genetic and cancer research. Since he has also been a director of the human genome project. The goal of this endeavor is to eventually identify all of the 50, tohuman genes.

Watson believes that this will make it easier to identify individuals who are at risk of developing a variety of genetically caused diseases. American Molecular Biologist. I n James Dewey Watson shared the Nobel Prize in Medicine with Francis Crick and Maurice Wilkins for their discoveries concerning the molecular structure of deoxyribonucleic acid DNA and its significance for the transmission of genetic information.

Molecular biologists have called the discovery of the double-helical structure of DNA one of the most important developments in twentieth-century biology. The structure of DNA proposed by Crick and Watson in immediately suggested insights into the nature of the gene, the genetic code, and mechanism by which information stored in DNA was transmitted from generation to generation.

Watson was born in Chicago, Illinois. We strive for accuracy and fairness. If you see something that doesn't look right, contact us! Martin Luther King Jr. Jimmy Carter. Bob Dylan. Alice Munro. Chien-Shiung Wu. Marie Curie. Henry Kissinger. The Discovery Crick's and Watson's first serious effort toward learning the structure of DNA came up short, but their second attempt, concluded in the spring of and resulted in the pair putting forth the double-helical configuration, which resembles a twisting ladder.
