The Discovery Of The Structure Of Dna

1. What role did Rosalyn Franklin play in our understanding of DNA’s structure? She discovered the double-helix position of the DNA.

I believe that Rosalind Franklin deserved more credit than she got foe her X-ray crystallography. Watson took photo 51 from her file without ther knowledge which showed that DNA has a definite pattern and two strands. Watson and Crick used the photo for their own personal gain instead of giving Rosalind any credit they saw Rosalind as below them so they had no issue stealing her idea.

Chapter 1: Genes can be demonstrated as “instruction books for making functional markers such as ribonucleic acid(RNA) and proteins”(Chapter 1, page 4). Distinctively, the four nitrogenous bases to code the gene of DNA is adenine, thymine, guanine, and cytosine. In addition, Rosalind Franklin was among the primitive people to experiment with X rays as a form of molecular photography in order to learn more about DNA and its structure. The structure of DNA taught a constitutional fact about genetics; it stated that the two strands of DNA were complementary to each other. Moreover, DNA replicates in order to make new sets of

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.

Discoveries in DNA, cell biology, evolution, biotechnology have been among the major achievements in biology over the past 200 years with accelerated discoveries and insights over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be most important and describe their significance to society, health, and the culture of modern life.

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)

Also he helped with mapping cancer to help people or warn others, so they will be able to find if they have it. James helped out everyone on this planet and those who are sick or are sick but don’t know it. To be recognized in the scientific community you have to do something amazing. Crick and James Watson's first look toward taking in the structure of DNA missed the goal, but their second look took place in the spring 1953 and brought about the match of the ladder helical look. Which takes after a stepping stool. Their model added how the DNA particle could copy itself. Watson and Crick had looked the work of English scientist Rosalind Franklin, a partner of Maurice Wilkins' at King's College London, to land at their noteworthy disclosure, notwithstanding, her commitment to their discoveries would go generally unrecognized until after her she died. Franklin had made a few unpublished working papers talking about the basic characteristics of DNA, and with her understudy Raymond Gosling had taken a X-ray diffraction picture of DNA, known as Photo 51, which would get to be urgent proof in recognizing the structure of

Nonetheless, today, she is more and more acknowledged – especially due to the recent rise of passionate feminists. Also, historian’s and archivist’s work over the past few decades has promoted Franklin and she has become more widely known. Numerous books and articles have been written about Franklin and the lack of credit she has received. In 2004, a university in Illinois, US, was renamed to Rosalind Franklin University of Medicine and Science in dedication to Rosalind Franklin. The university states “One thing is certain - she died without ever knowing the true magnitude of her contribution to the science of life”. Finally, one could say Watson actually did Franklin a favour, by portraying her almost villain-like in his book. Had he not done this, she might had been forgotten

“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.

I would cite the various colloquiums I gave elaborating on the two forms of DNA and my notebook for the deduction regarding the antiparallel and helical structure of DNA. I would also cite the article I wrote a month before I even saw the Watson and Crick model. Nonetheless, I believe that Franklin being the determined and strong-willed woman that she was, she would have found a way to justify her rightful claim to credit in the discovery of the structure of

“Science and everyday life cannot and should not be separated”; this seemingly simple statement is found in a letter written by Rosalind Franklin to her father. Over seventy years after this declaration was made, an abundance of people have proven its truth and unknowingly use this statement to influence their education and life. Although Rosalind Franklin underwent various trials throughout her life, generational research can attend that her persistence made her into the brilliant chemist that is still remembered today. Rosalind Franklin’s most recognized piece of work is her important contributions in understanding the structure of DNA, a remarkable discovery considering her unexpectedly short lifespan. When looking at the impact Franklin

to her career in the future since it was the technique used to get a

Rosalind headed back home to England in 1950. A physicist, John Randall of King's College, invited Rosalind into his research group. He told her that her sole project would be to "investigate the structure of certain biological fibres," meaning DNA. This is where a man named Maurice Wilkins first entered the picture. He was also a research associate in this group and played a controversial role later in Rosalind's life (McGrayne, 1993).

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.
