Rosalind Franklin: The Unrecognized Collaborator The video begins by introducing Francis Crick and James Watson and speaking about their contributions on the discovery of the double helix in DNA. However Watson and Crick could not have made their discovery without the research and contributions of one unrecognized scientist: Rosalind Franklin. The video talks about Rosalind’s early life and then shows us the legacy that she left behind in science. From an early age Rosalind was extremely intelligent

genetic engineering‚ and to many to name. James D. Watson had a huge impact on society with his co-discovery of DNA‚ from a young age he was very interested in science this fuelled his passion. With the help of others James and co-discoverer Francis Crick they cracked the cod of DNA. All this has led other important discoveries and breakthroughs like how we pass on traits though generations‚ how genes work with health and how we can improve it also in agriculture with new plants that are immune

observant. Francis Crick: He does the same research with Watson‚ they are both teammates. He is also eager to know what is in DNA and the relationship of it with the double-helix. Rosalind Franklin: A French woman who do the same research as Watson and Crick. She is sensitive and wishes to work without the help of Watson and Crick. Maurice Wilkins: I thought he wasn’t important in the presentation. Compare the research approaches/ styles/ attitudes of Watson and Crick with those of

the X-ray patterns kept improving‚ it helped Watson and Crick create the first DNA model. It helped them because the details of the X-ray got better so Watson and Crick was able to examine the hard to see stuff with ease. Also through the X-ray patterns it showed that the structure of DNA was helical. Watson was the one to see it was helical. This showed the cooperation of scientists. The other method I found was when Watson and Crick immediately knew that Paulings model was wrong and they did

In 1869‚ he extracted a substance from white blood cells that he called nuclein. What do you think he was actually extracting? 2.

Imagine if you made a groundbreaking discovery and your ideas were shared without your consent and then you were not credited for your achievement. Rosalind Franklin‚ a scientist‚ made a big revelation that led to the discovery of the structure of DNA. Her coworker shared it with other scientists and she was never credited for her work. Rosalind Franklin was born on July 25‚ 1920 in London‚ England in a Jewish household‚ during the time of flappers and advancement for women. In 1928 a law was passed

James Dewey Watson is the man known for his great contribution to science. He and Francis Crick created the Double-Helix which later helped many other scientists. James Dewey Watson was born April 6‚ 1928 in Chicago‚ Illinois. He is still alive today. Watson’s childhood was spent in Chicago‚ Illinois. As a child‚ he lived with being punier than other boys in class. The only consolation was his parents’ empathy — they encouraged constant trips to the local store for chocolate milk shakes

Scientists today have only made some changes to Watsons and Cricks original model but have kept major features of their structure‚ like

Among the audience listening that day was James Watson‚ who was particularly interested in finding out the structure of DNA. Soon after the conference Watson‚ who remembered just barely enough information‚ shared Rosalind’s findings with Francis Crick. With the information that he recalled they were able to create a scale 3D model of DNA; Watson hadn’t taken any notes during Rosalind’s presentation‚ so naturally some of the things he remembered were inaccurate which also led to the model being

was until February 28th‚ 1953 when scientists James Watson‚ Francis Crick‚ Rosalind Franklin‚ Raymond Gosling‚ and Maurice Wilkins made breakthroughs in the discovery the double helix structure of DNA. The story of their fame and success is portrayed in the movie The Race for the Double Helix. In this film‚ the scientists use two different techniques in their research of DNA. In the end‚ the double helix is discovered when Watson and Crick read a thesis that was written by Franklin. The thesis was
