The Discovery Of The Structure Of Dna

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.

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.

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

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

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

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).

Over the past 46 years there has been an increased in the number of people who are in favor of legalizing marijuana. In a survey conducted in 1969, “12 percent of Americans thought marijuana used should be legal” (Jones 1). Nothing really change in the 1970’s and 1990’s, but in 2000 it “exceeded 30 percent…and was higher than 40 percent by 2013” (Jones 1). Several reasons for this dramatic increase is that more Americans are becoming aware of its medicinal use, also how the legalizing marijuana can help boost in revenue, and “newer generations of adults are more in favor of marijuana, replacing the older generation of adults who aren’t” (Jones 1).

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.

Engaging with my community is important because I been helping people volunteer around me since middle school and continuing in high school because of the help I received in elementary. I wanted to help the elementary children because of all the support and help that I received. Helping them makes me think of when I needed help and received through people. I mostly helps with volunteering around with little kids in different elementary schools at my school district. I want them to be safe and help them during their hard times. I wanted to help people because I wanted people to understand what they are learning and have a good education. When I’m volunteering I help keep the children safe and cheer them on when they are competing.

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.

The purpose of his proposal is to provide inquiry and identify the best way to implement fundamental plans to individuals who wish to build and run a small business in addition to the lack of information they may bear on the importance and sustainability of protecting their networks and data against cyber-attacks.
