The Double Helix DNA Theory

Great Essays
1. Francis Crick

Crick discovered the relative distances of the repetitive elements in the DNA molecule, and the dimensions of the monoclinic unit cell which indicated that the molecule was in two matching parts, running in opposite directions. He also, in collaboration with Watson discovered the material that our genes are made of and put forward the model of the double helix DNA structure which included the measurements of the angels formed by different chemical bonds. Crick in collaboration with Watson showed that DNA could produce exact copies of itself and carry genetic information. Crick elaborated on the implications of the double helical structure of DNA by stating that the sequences of the bases in DNA form a code by which genetic

The model identified by Watson and Crick differed from the model previously identified as the model was a double helix structure as compared to the others which were either had distances that were too small as seen in van der Waal’s version of the DNA structure which made the forces that hold the structure together unclear especially the negatively charged phosphates near the axel which repelled each other. I do not think that Rosalind Franklin received enough acknowledgements from Watson and Crick. Watson and Crick were very ignorant towards the fact that Franklin was the funding member to their project as her research stimulated their discovery. Had they not seen the picture of Photo 51, Watson and Crick could have possibly taken longer to complete their research or even worse not completed it all. They all agreed that the work would be published solely as Watsons and Cricks, disregarding Franklin’s hard work and effort. Watson later went on to criticise Franklin as a person by calling her “unattractive’ and “cruel”, this just showed how unappreciative he was of Franklin and her research which ultimately led to the highlight of his …show more content…
Without the discovery of DNA several technologies and practical applications would have not been discovered as the structure of DNA has to be known for all of these to be effective, and all these discoveries contribute immensely to how we live as humans on this earth.
• In the field of Forensic, DNA plays a large role in the solving of cases especially in those of murder, theft and rape. The impact of DNA in forensic allows for the guilt or innocence of the suspect to be determined especially in instances where the identification of the victim can occur when their condition is unfamiliar to friends and family. So the discovery of DNA in the Forensic field has allowed for the accurate safeguarding of society through the criminal justice system.
• Without the discovery of DNA in the field of Agriculture then breeders would not be able to facilitate the breeding of animals that have a better resistance to diseases. The discovery also allows the problem of micronutrient deficiency to be addressed as the farmers to provide products that are higher in nutrition, which play a big role in countries such as Somalia, where the food that the population consumes consists of a small range of staple foods that are low in nutritional

    Despite all of the good that using science in criminal investigation has done. Like all things there have been some hiccups. DNA testing has both enhanced and eroded the status of forensic science in criminal cases. Conventional forensic disciplines were unable to identify a perpetrator with any true discrimination. For instance, conventional serology (the study antigen or antibodies) field analysis of blood group substances was largely used in sexual assault cases during the 1980s (Mosby's Medical Dictionary 8th edition, 2009).…

    1. DNA Structure and Function DNA is the type of organic compound that stores the genetic information in a living organism. DNA is made up of two strands of nucleotides, which include a phosphate group, five carbon sugar, and a nitrogenous base. Each individual strand in held together by strong covalent bonds (a bond formed as a result of the distribution of electrons between atoms). The two strands are then joined to each other by hydrogen bonds between complementary bases.…

    HOW HAS THE USAGE OF DNA IN FORENSICS AFFECTED THE COURT SYSTEM? DNA use in forensic science has made significant impact in criminal justice system over the past decade. DNA does not only play the role of a prosecution toll in the criminal justice system, but it is also used in forensic science as part of the post-conviction review that offers great help in the investigation process (Hauck, 2005). There has mixed feelings about the use of DNA in forensic in relation to the criminal justice system; some people feel that the use of DNA in forensics has helped find more evidence and prosecute criminals while other believe that in some cases DNA might be biased and indicate that the criminal was not involved in the crime because of lack of evidence…

    DNA was discovered through the collaboration of several scientists, most notably James Watson and Francis Crick. The two main methods used in the discovery of the structure of DNA was experimental, through X-ray crystallography, and theoretical, through building a model based upon the experimental data. Linus Pauling, James Watson, and Francis Crick were proponents of the theoretical model for the structure of DNA, while Erwin Chargaff, Maurice Wilkens, and Rosalind Franklin were champions of experimentation. Watson and Crick were the two who ultimately discovered the structure of DNA. They combined the findings of Chargaff, Wilkens, and Rosalind in order to formulate a “grand unifying theory” on the structure of DNA.…

    DNA testing is a major flaw in the criminal justice system that can be addressed through upgrading capacity of labs and the amount of DNA the DNA database can store. Imagine being wrongfully convicted for a crime you did not do and spending years behind bars all because the justice system didn't analyze the DNA correctly. This happens to many people every year throughout the country, and there are many problems and causes with DNA identification and there needs to be a solution for it. Wrongful convictions because of DNA is a problem in the justice system. Many cases have not even been tested for DNA.…

    If you had told someone in the early 1800’s that every cell in your body contains something called DNA made of molecules called nucleotides (DNA) that determine every characteristic about you, from your height and eye color to whether or not you’ll get a certain disease or condition, they would think you were crazy. Today, most students learn about DNA in middle school biology. DNA was first discovered by a German biochemist named Frederich Miescher in 1869, but its importance was not realized until 1953 (DNA). Genetic testing, “a type of medical test that identifies changes in chromosomes, genes, or proteins” (What is Genetic Testing?), however, was first done in the 1910s with ABO blood typing (O’Neil). Today, testing is used for determining paternity, determining a person’s chance of developing or passing on a genetic disorder, and to confirm or rule out a suspected genetic condition (What is genetic testing?).…

    It is beyond a doubt that the founding fathers could ever conceive an American society like the one we are living in today. The discovery of the structure of DNA marks a significant landmark in medical history. This has open the doors to a new realm that deepen our understanding of biological systems and promises a future that once was an abstract idea in science fiction novels. A challenge that my generation is facing is answering whether genetic modifications are ethical. Despite the ongoing debates, it is remarkable that this type of science is even possible, partially because of the universality of DNA.…

    Watson was born in Chicago in 1928 and graduated from the University of Chicago. He is an American biologist, geneticist and zoologist and is best known for his Nobel Prize winning discovery of the structure of DNA along with Francis Crick. He is also known for his work with the Human Genome Project and continues to be one of the most influential scientists in the past century. I chose to read this book because I had heard it had been around for quite some time and gave an inside look at how several scientists worked together to discover the structure of DNA. We had talked about Watson and Crick in high school and in my last book report there was a lot of discussion about the structure of DNA and I wanted to know about the history and how they it was actually discovered.…

    Forensic DNA is the process of using and collecting DNA from crime scenes to solve criminal investigations and to ensure accuracy and fairness in the Criminal Justice System. DNA profiling has grown significantly in the past years and has been extremely useful in identifying suspects, criminals and other people involved in the crime. If the suspect is unidentifiable, DNA evidence is compared to a DNA database to identify the criminal. DNA testing has both advantages and disadvantages many of which relate to ethical, emotional, economic and practicality issues. Research states that an increasing number of criminal investigations have used DNA testing to successfully identify the perpetrator.…
