Discovering the Structure of DNA
Events
DNA is the substance that causes bacterial transformation
1944
Oswald Avery, Colin MacLeod, and Maclyn McCarty did an experimental demonstration to prove this.
Proteins have a helical structure that is proved X-ray AND Chargaff rules were discovered
1947 - 1949
Researcher: Linus Pauling
Erwin Chargaff finds out that there are equal potions of T and A, and G and C in DNA.
First DNA model built by Watson and Crick AND Researches studied the structure of DNA using X-ray crystallography
1951 - 1951
James Watson and Francis Crick build a three stranded helix with bases on the outside and phosphates on the inside which the realize is wrong. Researches of X ray crystallography: Rosalind Franklin, Maurice Wilkins
DNA is the only material transferred from phage to bacteria when bacteria is infected AND "photo 51" proves DNA is a helix, Rosalind was working with the photo and didn't return it until 1953.
1952 - 1952
Researchers: Alfred Hersey, Martha Chase
Researchers: Rosalind Franklin
Wilkins shows "photo 51" without Franklin"s approval or knowledge. It provided the structural information they needed to finalize their model, completed on March of the same year.
30 January 1953
Researchers: Watson, Crick, and Wilkins.
Rosalind Franklin dies of ovarian cancer AND Watson, Crick, and Wilkins win the Nobel Prize in Physiology or Medicine
April 16, 1958 - 1962
She was 37 years old
Franklin was not acknowledged
CRISPER was discovered
1987
CRISPER is clusters of DNA that sis used to edit the base pairs of DNA. it was discovered by Yoshizumi Ishino.
Genetic code of the fruit fly is decoded (MODERN DAY EVENT)
2000
this was a major breakthrough, later leading to decoding human genomes done by Thomas Hunt Morgan.
The Human Genome Project was an international scientific research project with a goal of determining the sequence of nucleotide base pairs, and identifying all the genes of the human genome
April 14, 2003
The project was the biggest collaboration between biologists in history, it officially started in 1990 and it was finally complete in April 14, 2003. It was performed in twenty universities and researched in centers of the United States, the United Kingdom, Japan, France, Germany and China
Scientists discover a new strange DNA shape inside human cells. (MODERN DAY EVENT)
April 23, 2018
Scientists have discovered a new shape of DNA inside human cells. In a study published Monday, a team of researchers describe finding DNA as a four-stranded knot-like structure called an i-motif, inside human cells, creating new questions about what the role of this structure might be, if it even has one.
