Franklin was born on July 25, 1920, in London, to a wealthy Jewish family who valued education and public service. At age 18, she enrolled in Newnham Women’s College at Cambridge University, where she studied physics and chemistry.

What did Rosalind Franklin study?
Rosalind Franklin earned a Ph. D. in physical chemistry from Cambridge University. She learned crystallography and X-ray diffraction, techniques that she applied to DNA fibers.
Was Rosalind Franklin a biologist or chemist?
Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) was an English chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite.
What city did Rosalind Franklin perfect her work in crystallography in?
From 1953 to 1958 Franklin worked in the Crystallography Laboratory at Birkbeck College, London. While there she completed her work on coals and on DNA and began a project on the molecular structure of the tobacco mosaic virus.
When did Rosalind Franklin make her discovery?
She is best known for an X-ray diffraction image that she and her graduate student Raymond Gosling published in 19531, which was key to the determination of the DNA double helix. But Franklin’s remarkable work on DNA amounts to a fraction of her record and legacy.
Who really discovered DNA?
Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
Why didnt Rosalind Franklin get credit?
Franklin, whose lab produced the photograph that helped unravel the mystery of DNA, received no credit for her role until after her death. At the time of her death, she was working on the molecular structure of viruses with her colleague Aaron Klug, who received a Nobel Prize for the work in 1982.
What does DNA stand for *?
Answer: Deoxyribonucleic acid – a large molecule of nucleic acid found in the nuclei, usually in the chromosomes, of living cells. DNA controls such functions as the production of protein molecules in the cell, and carries the template for reproduction of all the inherited characteristics of its particular species.
Who stole Rosalind Franklin’s work?
One claim was that during the race to uncover the structure of DNA, Jim Watson and Francis Crick either stole Rosalind Franklin’s data, or ‘forgot’ to credit her.
How did Rosalind Franklin take a picture of DNA?
Her famous image of DNA called Photo 51 was made using a X-ray technique that did not require the sample to be in crystal form. She used this method since DNA, like some other big molecules, does not like to form a crystal. Instead, DNA prefers to form organized fibers.
Who are the 2 most determined DNA detectives?
Two of the most determined of the DNA detectives are Francis Crick and an American, James Watson. Also at the Royal Society is a 31 year-old British scientist named Rosalind Franklin. She is responsible for the crucial X-ray photo.
What did Watson Crick and Wilkins learn from photo 51?
From the image, Watson concluded that DNA was helical. During his meeting with Wilkins, Watson also obtained necessary dimensions of DNA derived from Photo 51 that he and Crick later used to develop their proposed structure of DNA.
Why was the first DNA model rejected?
Watson and Crick’s model erroneously placed the bases on the outside of the DNA molecule with the phosphates, bound by magnesium or calcium ions, inside. When ideas — like Watson and Crick’s first stab at a structure for DNA — don’t fit the available evidence, they are ultimately rejected or modified.
Did Rosalind Franklin discover the structure of DNA?
Rosalind Franklin made a crucial contribution to the discovery of the double helix structure of DNA, but some would say she got a raw deal.
Did Rosalind Franklin get a Nobel Prize?
In her short lifetime of only 37 years, Rosalind Franklin produced research that led to a Nobel Prize, yet she was not one of the awardees.
What two types of DNA did Franklin?
Franklin was a physical chemist who made pivotal research in the discovery of the structure of DNA, known as “the most important discovery” in biology. DNA itself had become “life’s most famous molecule”. While working at the King’s College London in 1951, she discovered two types of DNA called A-DNA and B-DNA.
