The greatest discoveries do not come from a single source. It takes many different sources coming together as one, a compilation of information to lead to a significant discovery. For example, in what seemed like a race for the double helix, several different scientists had to make excellent progress in their works. all of the different discoveries related to the broad subject of dna had to be mended together in order for the final discovery of the true structure of DNA. to come about.
Frederick douglas, born in Hale, England in 1879, was a bacteriologist who made the first progressive movement in gaining knowledge related to the structure of DNA. In 1928 he reported one of the first experiments suggesting that bacteria are capable of transferring genetic information via transformation. In his experiment, formally known as Griffith’s experiment, he used two strains of Streptococcus Pneumoniae (pneumococcus) bacteria to infect mice. The two types were type III-S and type II-R. Type III-S had a protective capsule that could shield it from the immune system of the host. In the experiment, bacteria from the type III-S strain were killed with heat and then the remains were added to th II-R strain bacteria. Although neither strain alone was harmful to the mice, the combination was lethal. when looking at the bloodwork of the dead mice. Griffith found live strains of both bacteria. He concluded that type III-S transformed into type II-R. This experiment showed that traits could be transferred from one organism to another. it was one of the first experiments to suggest that DNA was the genetic code because heat denatures protein, thus ruling out the possibility of protein being the genetic code. At this time, DNA was still poorly...

...ar structure of nucleic acids and its significance for information transfer in living material. They are both well known for their discovery of the double helix in 1953.
Although Watson and Crick were the ones who came out on top, discovering the double helix, it would not have been possible without the assistance of many other scientists; Rosalind Franklin in particular. Rosalind Franklin’s outstanding pictures of DNA and research on the matter of the location of the phosphate groups were what allowed Watson and Crick to finish their model. She was a brilliant scientist and unfortunately she was not recognized for her remarkable discovery. Rosalind Franklin died at age 37 of ovarian cancer which is thought to be an effect of the work she dedicated her life to. Working with x-ray crystallography exposed her to the excessive radiation that brought on the cancer.
Ted Bieler’s Helix of Life (1971) that is located outside the Medical Sciences building at University of Toronto is a sculpture made from a light grey concrete material. Its color appears to be plain which happens to match the exterior of the Medical Sciences building as well. Due to the age of the sculpture, it shows lighter and darker gray dents and streaks near the top and bottom and where it bends. Some of the markings have been made from the material and texture of the sculpture. The material used, which was said previously, is cast concrete. Using concrete without any smooth surface tools creates a rougher and coarse texture which is why it has dents and holes when viewing it up close. As the viewer looks at the sculpture from afar, its
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.
Many great scientists have found lost cities and great treasures, how? By making mistakes. Mistakes have led to great discoveries and rich people. Many errors lead to lost treasure, making new things, and you can learn from them; so you do not make the same mistake again. Therefore, mistakes are crucial part of a discovery.

How Watson and Crick’s Discovery of the Structure of DNA Influenced American Industries and Scientific Development in the United States
...or instance, hepatitis C virus), biological molecules (such as cyclic adenosine monophosphate), and Human Immunodeficiency (HIV) virus (Bauman et. al. 2011). Rosalyn had went farther in the world of science than anyone including her self thought was possible (Bauman et. al. 2011). Rosayln and Berson changed history, altered the way science was perceived and their time, and how today we see and research science.
Throughout history, we have come to significant inventions and discoveries that have influenced our lives greatly. It is obvious that these inventions and discoveries occasionally occur at the cost of making major mistakes, but are they always worth it? Errors can either lead to difficulties, and can also lead to development. So the real question is, “Are mistakes a key part of making discoveries and inventions?” Well, after gathering the facts, I think that mistakes are in fact a key part of discovering. There are many reasons as to why errors contribute to helping making inventions and discoveries, but I only have three. First of all, mistakes are an important part to making inventions because they help you determine what you did incorrect
Francis Crick: He does the same research with Watson and they are both teammates. He is also eager to know what is in DNA and the relationship of it with the double-helix, but at the same time is disorganised, and expected Watson to do a majority of work.
Rosalind Franklin The leader I have been researching is Rosalind Franklin. Rosalind Franklin is known for her contribution to the understanding of DNA and RNA. Rosalind Franklin is also commonly known for the famous photo 51 a picture taken by Raymond Gosling who was working under her supervision. She also found the tobacco mosaic virus which is a single stranded RNA virus.
...vercome, there is more of a chance to capture such great discoveries. People need to realize that if they never take the time to stop and look around, appreciate the small things in life, they might miss out on important details and or moments that the world has to offer. Scientist didn’t obtain their greatest discoveries by looking at the world with a closed mind. During the months of September through Novemeber, the leaves start to fall off the trees. It is obvious its fall, but what else is occurring? Gravity. Albert Einstein discovered gravity by watching and ordinary object fall. At that moment he became a scientific unscrupulous observer.
"The discovery of the structure by Crick and Watson, with all its biological implications, has been one of the major scientific events of this century." (Bragg, The Double Helix, p1) In the story of The Double Helix, James Watson tells of the road that led to the discovery of life's basic building block-DNA. This autobiography gives insight into science and the workings within a professional research laboratory that few members of society will ever be able to experience. It also gives the reader an idea of the reality of life for one scientist and how he struggled with the problem of DNA. However, the author's style is marked by his lack of objectivity and inclusion of many biased opinions and personal prejudices.
Through exploring the concept of discovery it is understandable that discovery can come in different forms. Discoveries and rediscoveries can only be brought up through experiences which bring about realisation within an individual’s mind. Also the value of a discovery will differ from an individual to an individual depending on the effort that has been taken to make that discovery.
...his day. These men have made an enormous amount of discovery to get medicine to where it is today.
Ultimately, both scientists with further research and experiments, further proved Mendel's findings and even improved them allowing us to further understand genetics in a sense that we would not have been able to comprehend.
DNA (deoxyribonucleic acid) is a self-replicating molecule or material present in nearly all living organisms as the main constituent in chromosomes. It encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Simply put, DNA contains the instructions needed for an organism to develop, survive and reproduce. The discovery and use of DNA has seen many changes and made great progress over many years. James Watson was a pioneer molecular biologist who is credited, along with Francis Crick and Maurice Wilkins, with discovering the double helix structure of the DNA molecule. The three won the Nobel Prize in Medicine in 1962 for their work (Bagley, 2013). Scientist use the term “double helix” to describe DNA’s winding, two-stranded chemical structure. This shape looks much like a twisted ladder and gives the DNA the power to pass along biological instructions with great precision.
