Is Microbiology Important In History

The pictures were shown to James Watson and Francis Crick by Maurice Wilkins. They were then able to confirm their theory about the 3D structure of DNA. In 1962, they were awarded the Nobel Prize in Physiology or Medicine for solving the structure of DNA. The Nobel committee could not award it to Franklin because the Nobel prize could only be shared by three people and also because she was already dead (DNA from the Beginning, 2011)

The discovery of deoxyribonucleic acid, more commonly known as DNA, has been the foundation for much scientific work. This fundamental discovery was credited to James Watson and Francis Crick. Many people believe that another person, Rosalind Franklin, also played a large role in the research. How much did she contribute to the discovery? Why is her name left unrecognized? This paper will discuss her part in the search and whether her name should appear next to Watson's and Crick's as the co-discoverer of DNA.

Over the course of the modern age, the human body was still a mystery waiting to be solved. The body contains secrets one can only hope to discover. Over the twentieth century, scientists tried to understand one of the most complex concepts in the biological field. DNA (Deoxyribonucleic acid) was at the forefront of research. Several theories claimed to have solved the structural concept of DNA. However, it was not until Francis Crick and James D. Watson discovered the true structure, the double helix. However, many potential models of DNA had passed through the biology field until eventual lose of credibility. The past models would contain a fixed detail that would make the entire concept invalid. In James D. Watson book, The Double Helix, he illustrates his path amid incorrect theories until he reaches the model that is taught around the world today.

2. What role did James Watson & Francis Crick play in our understanding of DNA’s structure? They discovered the 3D structure.

Watson and Crick discovered that cell’s nucleuses contained a molecule that was called deoxyribonucleic acid, or DNA. The clues from the diary are: “Even us lab boys knew that there had been gossip going around the labs that Crick and Watson had been trying to solve the structure of this new-fangled molecule called DNA – deoxyribonucleic acid – but discovering the secret of life itself?”

With a competitive spirit, people are driven to act in ways that they would not otherwise and the results can be drastic. In the case of James D. Watson and Francis Crick, in Watson’s novel the Double Helix, this sensation of competition leads to one of the greatest discoveries in biology. But the actions of Watson, Crick, and their competitors may or may not be justified for the results that they yield; the powerful conflict of rivalry has beneficial, detrimental, and questionably moral consequences that shaped the pathway to DNA’s structure.

The discovery of the structure of DNA was one of the most important scientific achievements in the last century, in human history, in fact. The now-famous double helix is almost synonymous with Watson and Crick, two of the scientist who won the Nobel Prize for figuring it out. But there is another name you may know too, Rosalind Franklin. You may have heard that her data supported Watson and Crick’s brilliant idea, or that she was a belligerent scientist, which is how Watson described her in his book The Double Helix. But thanks to Franklin’s biographer, who investigated her life and interviewed people close to her, we now know that that account is far from true, and her scientific contribution have been vastly underplayed. Let’s hear the real story of Rosalind Elsie Franklin, the woman who influenced the modern medicine and world by contributing the most in discovering the structure of DNA, coal and viruses.

“Science and everyday life cannot and should not be separated” –Rosalind Franklin she thought of science as her life. Rosalind Franklin was one of the leading contributors to what is now known as the DNA theory in today’s society. Ms. Franklin helped lay the groundwork for the research and theories that were later developed by James Dewey Watson and his partner Francis Cricks. The DNA theory as we know it today may not be, had it not been for Rosalind Franklin.

Two scientists from Cambridge University named James Watson and Francis Crick were the first ones to actually build the actual structure of the DNA molecule. In building their DNA molecule, they discovered that there were two different types of bases, purines and pyrimidines. Purines were the larger of the two types of bases, and are the double ringed structures [example of nucleotides that fit in this category are adenine (A) and guanine (G)]. Pyrimidines were the smaller of the two types of bases, and are the only single ringed structures [example of nucleotides that fit in this category are cytosine (C) and thymine (T)]. The two scientists also discovered that in the DNA molecule, only two base pairings of nucleotides are possible, adenine (A) with guanine (G) and thymine (T) with cytosine (C). This is because of the improper forming of hydrogen bonds. In a G-C pairing, three hydrogen bonds are formed whereas in an A-T pairing, only two hydrogen bonds are formed.

Rosalind Franklin was able to take an x-ray image of the DNA strand and see how it was shaped. After seeing her work James Watson and Francis Crick took her image and began researching into it. This led them to discover the double helix.

Rosalind Franklin was one of many female scientists robbed of credit for a major discovery of DNA. She was the first person to determine DNA also the first women. James Watson and Francis Crick were also trying to determine the structure of DNA and stole it from her. When they spoke to Wilkins, he went behind Rosalind’s back and showed them her image of DNA without her permission or knowledge with out her knowing.

Rosalind Franklin, a name mostly forgotten in textbooks, majorly contributed to the discovery of DNA’s helical structure. Unfortunately for her, her contribution was made during a time when feelings of misogyny and antisemitism were prevalent. As a result, she never received the recognition she deserved from her male competitors. Photographs that she had taken and reports that she had written were unknowingly given to rival scientists, Francis Watson and James Crick, Photograph 51 being the most prominent among them. This led them to determining DNA’s structure and acquiring international fame. Had her information not been leaked, Rosalind would’ve had a very good chance of discovering it first. Franklin changed the world of science with Photograph

Although DNA was initially observed by Frederich Miescher, a German biochemist near the end of the nineteenth century, the key to the structure of DNA was not discovered until almost a hundred years later. It was at that time that science realized the importance of DNA to the study of biology.

Rosalind Franklin’s work on DNA was crucial in discovering the composition of the human body as a whole. Her x-ray photo revealed a double helix structure and she also discovered the A and B form of DNA. She worked through the adversity of being a female in a predominately male dominated realm and made remarkable findings that were eventually stolen. She adapted to a new lab with antiquated technology. Before this discovery, the structure of DNA was thought to be simple. Scientist, Watson and Crick, started with the wrong structure of DNA from a misinterpretation of notes from one of Franklin’s presentations. Unlike Watson and Crick, Rosalind Franklin could explain DNA and how it worked.
