How Did Rosalind Franklin Contribute To Science

581 Words3 Pages

Rosalind Franklin Rosalind Franklin helped contribute to one of the greatest breakthroughs in science. She was born in London in 1920 and she was raised by a very wealthy and educated family. Rosalind Franklin was easily described as hardworking and the best at everything - the best at science, at math, and at all the other sports she participated in. Franklin arrived at King's College London, and in January, 1951, her new assignment was to discover the structure of DNA. At the time when Rosalind Franklin started working on DNA, it wasn't at all clear what DNA really looked like or how it might work. Franklin did most of the professional work in the lab and she was able to capture excellent pictures of DNA. Within that time, Franklins discovery that there are two forms …show more content…

After watching this video, I learned that from the DNA structure, the A is a drier, more crystalline form of DNA and produces more detailed images. The B is wetter and how DNA occurs in living cells. The X shape in the middle is the diffraction signature of a helix. I found it very interesting how we understood the concept of DNA back then and we realized how important it was being that it contained genetic material and the blueprints for every cell in our body, yet we still needed to explore what it really looked like and how it worked. This is related to the things we have covered in class because we have already studied DNA. In this course, we have studied the many characteristics of DNA which include that it is double helix that contains genetic material and it is kept stable by hydrogen bonds. DNA is made up of smaller units called nucleotides. In turn, each nucleotide consists of a phosphate group, a sugar and a nitrogenous base. DNA also include base pairing which is the 'copying' mechanism for DNA. In DNA, bases are the adenine base, which only pairs with a thymine

Be it a perennial basketball all-star, a platinum-record producing artist, or an author whose name seems to be permanently etched onto bestseller lists – I respect anyone who is a titan of their craft, a groundbreaking trailblazer who redefines whatever they do. Rosalind Franklin was the manifestation of an extraordinary person. A remarkable scientist, Franklin received a PhD from Cambridge University when women maintaining desires beyond becoming housewives were ridiculed. Franklin later became a fellow at King’s College, where her work on X-Ray Diffraction revealed the structure of the most important molecule in science: DNA.

Galileo's scientific investigation or discovery is a very important one, because it is still being taught in science classes through out the world today. Along with Galileo's scientific investigation Bacon's scientific investigation is just as important as Galileo's discovery because the testing of hypotheses is also still being taught in school's today and has allowed society to make many scientific and medical advances.

Benjamin Franklin was very curious and him being smart led to him making very good science claims. It stated in the text by Benjamin Franklin,"was the discovery that electricity was “not created by the friction, but collected only.” Only a man like Benjamin Franklin could find out that friction was not created but collected. Benjamin Franklin would not fool around with the science world he was very serious about the science world and that ' why he is well known in our world today.

    As a girl, she faced some opposition from within the family, as her father did not believe in a higher education for women. He had wanted her to be a social worker, but Rosalind ultimately enrolled at Newnham College in 1938. Later on, she met Maurice Wilkins in John Randall 's laboratory at King 's College, London while working there as a research associate. Despite her extensive work on the DNA project, Wilkins saw her as a technical assistant because of the number of restrictions women had at the time (https://goo.gl/p1XZbH). Rosalind Franklin was also born of a Jewish family, so she faced some anti-semitism as well as discrimination for her strong personality, Maddox writes in the biography, Rosalind Franklin: The Dark Lady of DNA.
