Rosalind Franklin was an English chemist and x-ray crystallographer. She is known for the understanding of the molecular structures of DNA , RNA , viruses, coal, and graphite (wikipedia). She used radiation to confirm the DNA density and
Rosalind Franklin As hard as is it is today for women to succeed in the sciences, one must give kudos to those that came before us. These are the women that paved the way for today's generation of women scientists. One such woman is Rosalind Elsie Franklin, a chemist who had a great impact on the modern day field of genetics.
Understanding DNA can take a lot of studying and confusion to even get the general idea of the concept. The structure of DNA is very complicated and complex to understand, but researchers James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin all developed the idea of the DNA structure in 1953. Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including adenine,
Abstract This paper explores the history and some interesting facts about DNA. The last couple centuries have seen an exponential growth in our knowledge of DNA. The history of the DNA can be traced back to multiple devoted scientist. This article attempts to summarize, and review the basic history of DNA while providing some fascinating information about it.
Who Discovered DNA? Heather Kane 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.

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.
The definition of honor is the regard with great respect. My definition of honor is to recognize those who have helped people somehow in any way, shape, or form. James was involved in the co-discovery of the double-helix structure of DNA along with Francis Crick. James Watson received a Nobel
“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
If I was Rosalind Franklin reading “The Double Helix” in 1968, then it would be immediately apparent to me the insulting connotation with which I was referred to in this book. Even a simple choice to refer to me using the nickname “Rosie” is derogatory as it minimizes my portrayal
One of the most important things discovered and understood in biology within science, has been the discovery of the DNA structure. Where DNA is the abbreviation for deoxyribonucleic acid, though it is more known by nearly everyone simply as DNA. The idea behind DNA is that it is a self-replicating material that can be found in all living organisms, especially humans. The structure of DNA was solved in the year 1953, and was solved by four very important scientists who were; Francis Crick, Rosalind Franklin, James Watson, and Maurice Wilkins (Silverman, 2003). Franklin was seen to contribute to the DNA structure heavily through her own research and discoveries, while it was noted that both Crick and Watson worked together on their discoveries and research. It has been seen that Wilkins contributed less than the other three, but in saying this, he still helped with it and this was made obvious when he also received the Noble Prize. The Noble Price was awarded to Crick, Watson and Wilkins in 1962 for the discovery and solution of the DNA structure (Silverman, 2003). Unfortunately, although Franklin had a big part in the discovery she was not awarded the Noble Prize, as she passed away in the year 1958 (Klug, 1968). If she was still alive at the award ceremony she would have received it alongside the other three. But it should be made clear that she was an important scientist during this discovery, which is seen through what she discovered. These four scientists all contributed
In 1953 four scientists: James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin completed a DNA model which they created using observed X-ray diffraction patterns. This model showed how the structure of DNA was able to transmit genetic information from parents to their offspring.
In 1962, the Nobel Prize was awarded to Francis Crick and James Watson for formulating the structure of the complex molecule known as DNA. These discoveries were a direct result of the accumulation of many scientists’ earlier analyses and findings of the DNA. Before Watson and Crick had developed the double-helical structure of DNA, indication of this genetic material had been revealed around the 1850’s. During the century following the first evidence of DNA, subsequent researchers had been eagerly examining the physical and chemical components of this molecule. Moreover, scientists such as Erwin Chargaff and Linus Pauling established a scientific foundation of research for future experts like Watson and Crick to analyze and interpret. The history of science acknowledges Watson and Crick’s findings as an exclusive discovery of their studies. However, the knowledge required to expose these innovative ideas are a culmination of “human events in which personalities and cultural traditions play major roles” (Watson and Stent, 3). Watson’s personal account within The Double Helix introduces the significance of these scientific influences on his research and discovery of the DNA molecular structure. Without major scientific figures, such as Max Perutz, Rosalind Franklin, and Linus Pauling, the conceptualization of Watson and Crick’s DNA structure would not have successfully developed as it did in the 1950’s.
The history and mysteries of DNA continue to fascinate biologists and chemists alike. However, we must question, who was the first to discover DNA, and what scientists have done to further enhance our understanding of it? In short, DNA was first isolated by physician Friedrich Miescher in 1869; in 1937, William Astbury became the first person to produce an x-ray diffraction pattern of the DNA molecule. Sixteen years
Rosalind Franklin was a chemist who made a profound contribution as a result of her work with DNA. Prior to this time, DNA was still a mystery in how impactful its purpose could be to society and the growing age of science and technology. DNA became of importance to learn about the foundation in relation to genetic and hereditary. Without the contribution of Franklin, todays understanding of the DNA structure would not exist. Rosalind Franklin died before the Nobel Peace Prize was given for the discovery of DNA. If she been alive, her receipt of the award would have been justifiable. Despite her death, Rosalind Franklin demonstrated the knowledge and research essential for understanding deoxyribonucleic acid and as a result should receive recognition in the form of a Nobel Peace Prize.
