The Importance of the Structure of DNA
Ka Zhu
The Importance of the Structure of DNA Understanding ideas at a macroscopic scale is simple. Looking at a clock, observing and understanding the movements of the hands over the numbered surface are, in essence, all one requires to use the device. In order for innovation to occur, it is imperative to understand the inner workings of the device on a microscopic scale to modulate its properties. Such is the case for many innovations in science, from the heat engine to penicillin, and is no different for biological advancements. Like the seed of a plant, the understanding of the structure of DNA constitutes the basis of all life, establishing a foundation upon which explanations of increasing complexity can be developed. In the eyes of Thomas Kuhn, though the discovery of DNA was necessary for the understanding organisms, it was not a revolution due to the cumulative development of biology alongside the discovery of the DNA structure, the lack of conflict between scientists, and the absence of anomalies in the scientific paradigm in the 1950s (Kuhn, 92-94). On the other hand, this discovery was indeed revolutionary in that it formed such an important biological foundation that has allowed civilization to recognize a new microscopic dimension in their surroundings, allowing for tremendous technological advancement, growth and the expansion of knowledge
Schrödinger questioned many biological conundrums in his article “What is Life?”, one being why the human body was so large in comparison with the single atom (Schrödinger, 2). He attempted to use “the naïve physicist’s approach” to the subject by wondering about the mechanisms and behaviours of organisms modeled using a physical mindset (Schrödinger, 2). Though he was successful in explaining many biological phenomena such as meiosis, gene transfer and mutations without great reliance on biological knowledge, he noted in his conclusion how one must be prepared to discover instances where it is impossible to

    Rosalind Franklin was a chemist who made the first DNA structure in 1953. A DNA model is a model of someone's DNA. DNA stands for Deoxyribonucleic Acid.A DNA strand is used to figure out a person’s physical and mental information. There are two forms of DNA an “A” form and a “B” form. (Franklin 2015) Franklin found this out by putting a DNA fiber under a x-ray machine Franklin refined herself. Franklin and Maurice Wilkins used Franklin’s x-ray photo called photograph 51 and Wilkins published first and so he got a nobel peace prize in 1962. (Franklin 2015) Franklin was then given some of the credit and was written about in the article of the newspaper.…

    * There has been a major effort in the history of science to figure out the structure of DNA. Having a double standard helix DNA has a uniform a diameter in its entire length. The helixes fit within a defined three dimensional space because they are both right handed. Polynucleotide chains are held together by the bases in the (center) hydrogen bonding with the bases on the opposite polynucleotide. Two polynucleotides are form around the outside of the helix with the bases extending into the center. Known as complementary base pairing; hydrogen bonding is a very specific process. Scientist had identified all the atoms and knew how they were bound together. What was not understood was the capacity to store genetic information, copy it and pass it from generation to generation, and the specific three dimensional arrangements of atoms that gave DNA its unique proprieties.…

    * Max Perutz – was the head of the unit where Crick works at Cambridge University. Perutz also shared important X-ray crystallography imagery with Watson and Crick that he had received from Maurice Wilkins and Franklin. Whether he was supposed to give this information to Watson and Crick without Franklin’s knowledge is unknown, nor is it entirely known how important her work was to the discovery of the structure.…

    Many don’t know that this information is false. DNA was actually first discovered in the late 1860s by Friedrich Miescher, a Swiss chemist. He found a new compound he called “nuclein” from the nuclei of cells. This is now called nucleic acid, which is the “NA” part of DNA (deoxyribo-nucleic-acid). Earlier, a monk Gregor Mendel conducted a series of experiments with peas, and “his observations turned out to be closely connected to the finding of nuclein,” according to the “Noble Prize” website. He proved that certain traits we inherited in different “packages”, what we now call genes. Watson and Crick were attempting to discover the structure of DNA in the early 1950s at Cambridge University, racing against Maurice Wilkins and Rosalind Franklin at King’s College. Wilkins and Franklin used an experimental approach to the study, according to nobelprize.org, “using x-ray diffraction to understand the physical structure of the DNA molecule.” Most scientists studying the structure of DNA were using similar methods. However, Watson and Crick used stick-and-ball models, physically building them, to “test their ideas on the possible structure of DNA.” They wasted much time and work at one point, after being misled from Watson remembering a few specific numbers from Franklin’s speech about her new discoveries on DNA. Later, they took a crucial step, and suggested that “the molecule was…

    Studying DNA can be extremely tedious and overwhelming. When Francis Crick and James Watson introduced the double helix, it was easy, for scientist, to comprehend the system, but it was rather difficult to understand how the DNA genes made proteins, which is the vital part. To fully grasp this concept scientist had to not only examine DNA, but they had to study RNA as well. The dispute, however, with DNA is that it actually is an elaborate and intricate code where these codes conceal its instructions.…

    Technology has had a profound impact on the development of cell theory, allowing scientists to view the components of organisms on an unprecedentedly small scale. Before the creation of microscopes, misconceptions about how organisms were originated arose. The idea of spontaneous generation, a theory held for nearly two millennia, proposed that organisms originated from inorganic matter. The lack of technology impeded on the development of cell theory, until the creation of the microscope.…
