1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30] 1953: DNA structure is resolved to be a double helix by James Watson, Francis Crick and Maurice Wilkins. [31] 1955: Alexander R. Todd determined the chemical makeup of nitrogenous bases.
Using these x-rays and information already known about the chemistry of DNA, James D. Watson and Francis Crick demonstrated the molecular structure of DNA in 1953. [ 22 ] [ 23 ] Together, these discoveries established the central dogma of molecular biology , which states that proteins are translated from RNA which is transcribed by DNA.

Rosalind Franklin joined King's College London in January 1951 to work on the crystallography of DNA. By the end of that year, she established two important facts: one is that phosphate groups, which are the molecular backbone for the nucleotide chains, lie on the outside (it was a general consensus at the time that they were at the inside); and the other is that DNA exists in two forms, a ...
Rosalind Franklin: The Dark Lady of DNA is a biography of Rosalind Franklin, a scientist whose work helped discover the structure of DNA. [1] [2] It was written by Brenda Maddox and published by HarperCollins in October 2002. [3] A play based in part on the book, Photograph 51 written by Anna Ziegler, was staged in London in 2015 starring ...
The women — both from the Midlands area of England — found out that they went to different parents after being born in the same hospital in 1967 in the first documented incident of babies ...
When she was a young girl, her parents determined that Eleanor, a "feminine" and "delicate" name, was not appropriate for her, and chose Barbara instead. [ 4 ] [ 6 ] McClintock was an independent child beginning at a very young age, a trait she later identified as her "capacity to be alone".
Modern genetic analysis began in the mid-1800s with research conducted by Gregor Mendel. Mendel, who is known as the "father of modern genetics", was inspired to study variation in plants. Mendel, who is known as the "father of modern genetics", was inspired to study variation in plants.
