Birth: Watson was born on April 6th, 1928 in Chicago,United States .
Year they became famous: In 1953 he and Francis Crick discovered that DNA was a double helix structure.
Publications that made him famous: he published "the Double Helix" which included his findings on DNA in 1968.
Contributions to the world of genetics: Watson's discovery of the double helix structure of DNA help scientists better understand how DNA functions and other categories on DNA such as cloning, hereditary traits,and genes.
Birth: September 25th, 1866 in Kentucky, USA.
Death: December 4th, 1945
Year they became famous: He began his research on the fruit fly in 1909, and he recieved his Nobel Prize in 1933 for his research on heredity.
Publications that made him famous: He published many books, one of his first being "Mechanisms of Mendelian Heredity" in 1915.
Contributions to the world of genetics: his intensive study of the fruit fly, which teachs scientist about heredity of traits and genes.
Dr. Kary Banks Mullis
Birth: December 28, 1944 in North Carolina, United States.
Year they became famous: In 1983 he developed the Polymeraise chain reaction.
Publications that made him famous: He recieved the Nobel Prize in chemistry in 1993 for his discovery of PCR.
Contributions to the world of genetics: His discovery of PCR made a great contribution to the world of genetics; now one molecule (usually DNA) can be amplifide to billions more molecules for detailed research to be conducted.
Barbara McClintock
Birth: June 6th, 1902 in Hartford, Connecticut.
Death: September 2nd, 1992
Year they became famous: in 1930 she was the first person to explain the details of crossing over in meiosis.
Publications that made her famous: in 1931 she published the first genetic makeup of her research on maize. Also in 1950 she published a paper on how genes can change their loci on a chromosome, her paper was called "The origin and behavior of mutable loci in maize."
Contributions to the world of genetics: Her studies on genetic transposition told scientists alot about genes and how they can behave, such as "jumping" from one area of a chromosome to another area. McClintock proved that some genes don't always stay in a fixed spot on a chromosome.
Roaslind Franklin
Birth: July 25, 1920 in London, England.
Death: April 16, 1958 in London, England.
Year they became famous: 1952 when she made the first photograph of the DNA's X shape, which later paved the way to prove that DNA's structure is a double helix.
Publications that made her famous: in 1953 Roaslind Franklin published an article in Nature on the DNA which included her famous DNA x-ray.
Contributions to the world of genetics: Rosalind Franklin developed the basis of what DNA's structure is (the double helix), with her x-ray of DNA, which showed an X formation.
