c. Methodical: Franklin was known for her meticulous attention to detail and thorough approach to her experiments.
d. Strong-willed: She had a strong personality and was not easily swayed by others' opinions.
e. Private: Franklin was known to be a private individual and preferred to focus on her work rather than socialize.
3. Rosalind Franklin's work was focused on perfecting the technique of X-ray crystallography. She used this technology to study the structure of DNA.
4. Watson and Crick planned to determine the structure of DNA by building models based on existing data and making educated guesses. They also sought additional insights from other scientists, including Franklin's work.
5. When Rosalind Franklin visited the Cavendish lab to view Watson and Crick's first model of DNA, she was unimpressed. She felt that their model was not accurately representative of the data she had collected through her X-ray crystallography experiments.
6. Photo 51 refers to an X-ray diffraction image of DNA taken by Rosalind Franklin. It was a critical piece of evidence that helped Watson and Crick in deducing the structure of DNA.
7. X-ray crystallography has advanced since Franklin's time in terms of technology, sensitivity, and resolution. Modern methods allow researchers to generate more detailed structures and analyze smaller crystals.
8. During World War II, Rosalind Franklin made important contributions to the war efforts by working on the properties of coal and its use for gas masks and island landing strips.
9. After leaving King's College, Franklin moved to Birkbeck College and continued her research on the tobacco mosaic virus. She made significant contributions to the understanding of the virus's structure.
10. Rosalind Franklin died of ovarian cancer at the age of 37 in 1958.
11. The cause of her ovarian cancer is thought to be exposure to radiation while conducting her research, as X-ray crystallography involves intense X-ray radiation.
12. Watson and Crick published their discovery of the double helix structure of DNA in the scientific journal Nature in April 1953.
13. James Watson, Francis Crick, and Maurice Wilkins received the Nobel Prize in Physiology or Medicine in 1962 for the discovery of the double helix structure of DNA.
14. Rosalind Franklin did not receive the Nobel Prize primarily because the Nobel Prize is not awarded posthumously, and she had passed away by the time the prize was awarded in 1962. Additionally, the Nobel Prize is typically awarded to a maximum of three individuals, and the committee recognized Watson, Crick, and Wilkins for their contributions to the discovery of DNA's structure. However, Franklin's critical work and contributions have since been acknowledged and appreciated.
1. The discovery of the double helix structure of DNA is attributed to James Watson and Francis Crick.
2. Characteristics used to describe Rosalind Franklin as a person/researcher:
a. Brilliant: Franklin was known for her intelligence and scientific acumen.
b. Determined: She had a strong work ethic and was dedicated to her research.
c. Independent: Franklin was fiercely independent in her scientific pursuits.
d. Detail-oriented: She paid meticulous attention to detail in her experiments.
e. Pioneering: Franklin's work laid the foundation for the understanding of DNA's structure.
3. Rosalind Franklin's work involved perfecting the technique of X-ray crystallography, which she used to study the structure of biological molecules, including DNA.
4. Watson and Crick planned to determine the structure of DNA by building models based on the available experimental data and using their knowledge of chemistry and biology to propose a viable structure.
5. When Rosalind Franklin visited the Cavendish lab to view Watson and Crick's first model, she was disappointed since the model significantly deviated from her own findings and she felt her contributions were not acknowledged.
6. Photo 51 is an X-ray diffraction image of DNA taken by Rosalind Franklin and her student Raymond Gosling. It provided critical evidence that the structure of DNA was helical.
7. X-ray crystallography has advanced significantly since Rosalind Franklin's time. Modern technology allows for higher resolution and faster data processing, allowing researchers to study complex biological structures in greater detail.
8. Rosalind Franklin contributed to the war efforts of WWII by working on coal and graphite research, which aimed to improve the efficiency of fuel sources during the war.
9. After leaving King's College, Rosalind Franklin discovered the structure of the tobacco mosaic virus through X-ray crystallography.
10. Rosalind Franklin died of ovarian cancer at the age of 37.
11. It is believed that Rosalind Franklin's exposure to X-ray radiation during her research may have contributed to her developing ovarian cancer, but this is still a subject of debate and ongoing research.
12. Watson and Crick published their discovery of the double helix structure of DNA in a paper titled "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid" in the journal Nature in 1953.
13. James Watson, Francis Crick, and Maurice Wilkins received the Nobel Prize in Physiology or Medicine in 1962 for their discovery of the DNA structure. Rosalind Franklin had passed away by the time the Nobel Prize was awarded, and it is against Nobel Prize rules to award posthumously.
14. Rosalind Franklin did not receive the Nobel Prize because the Nobel Prize is not awarded posthumously, and her significant contributions to the discovery of the DNA structure were not fully recognized at the time. However, her work has been acknowledged and she has gained recognition posthumously for her crucial role in the field of molecular biology.
