What Similarities and Differences Are There Between Historical and Scientific Explanations?
It is in our human nature to explain everything. Naturally, there are many ways of knowing.
Application of these, often defined by certain methodology, are frequently classified into areas of knowledge. Therefore it is natural for one to see similarities and differences within the process of attaining knowledge in different areas of knowledge. When the method forming scientific and historical models for human understanding of the world are examined, many similarities can be seen. These differences and similarities can also be seen when products of explanations are assessed. When scientific and historical explanations are compared one can see many similarities.
Empirical evidence are used in both scientific and historical explanations. For example, scientists have found a viable model of Deoxyribonucleic Acid (DNA) replication through empirical evidence. In
1958, Matthew Meselsohn and Franklin Stahl devised and executed an experiment to study DNA replication1. They attached two isotopes of nitrogen to each strand of DNA to determine what proportions of the isotope were present in DNA strands after multiple replication process. They observed that after one replication of DNA, each new molecule of DNA possessed one strand with the heavy isotopes of nitrogen. This evidence showed that the replication of DNA is semiconservative – the idea of copying via template2. The use of empirical evidence helped to explain the DNA replication process, even though one could not see the actual strands of DNA replicating. Looking at historical explanations one can see similar applications of empirical evidence. For example, historians such as
John Lewis Gaddis came up with theories about the cold war. From observing policies of the United
States and the Soviet Union, Gaddis have formulated theories about spheres of influences, and how these spheres of influences led to rising tension between the two super powers and eventually to the cold war. One may conclude that this

    Radioisotopic labels would be used in experiments to identify semi-conservative replication in prokaryotes. Because we anticipated that a labeled DNA would have different density with unlabeled, which means, by analyzing the different density of DNAs, we can determine which of DNA is labeled, half-labeled or unlabeled. To this end, I will use c13 label the bacteria and abruptly change carbon source with C12. Then I will collect four samples in different time and analyze the results from centrifugal by ultraviolet absorption.…

    Throughout the course of the Cold War, several themes can be seen to surface repeatedly. However, two themes can be seen to come afloat above the rest. They are the Nuclear Arms Race, and the battle of spheres of influence; both of which turned out to be crucial factors in the start and development of the Cold War. The former is comprised of the military aspect, while the latter is made up by the political aspect of the Cold War…

    BSC2011C Final Review Unit 1 Review Ch. 25, 22, 23, 24, 26, 19, 27 Ch. 25 1. Life is metabolism and heredity. Metabolism is the mechanism that creates order and complexity from chaos, by acquiring and expending energy. Heredity is the ability of an organism to copy itself and it is broken down into: i. Multiplication, ii. Inheritance, iii. Variation. 2. DNA codes via RNA for 20 of naturally occurring amino acids. Amino Acids are the building blocks of proteins and bodies. DNA stores and transmits hereditary information, but proteins do most of the work. DNA IS THE UNIVERSAL DIGITAL CODE FOR LIFE. To replicate and synthesize proteins, DNA relies on the pre-existence of protein molecules and RNA molecules. 3. RNA is the bridge between DNA and proteins, via mRNA for transcription and rRNA for translation. Thus, RNA can survive on its own while DNA relies on the existence of RNA and proteins, with them DNA is helpless. 4. The 4 points of “first life” are: 1. The Abiotic (non-living) synthesis of small organic molecules, such as amino acids and nucleotides. 2. The joining of these small molecules into macromolecules, including proteins and nucleic acids. 3. The packing of these molecules into “protobionts,” droplets with membranes hat maintained an internal chemistry different from that of their surroundings. 4. The origin of self-replicating molecules that eventually made inheritance possible. 5. The first cells to develop occurred in this order: Monomers > Polymers > Protobionts > RNA ‘world’ > DNA protobionts > first cell. 6. Fossils are the evidence of life and evolution. Organisms trapped in sediment > remain mineralized with hard and soft parts. 7. Fossils can be dated by two methods: Radiometric dating & Magnetism. In Radiometric dating, the age is based on the decay of radioactive isotopes. A radioactive “parent” isotope decays to a “daughter” isotope at a constant rate. The rate of decay is expressed by the half-life, the time requires for 50% of the parent…

    DNA replication is a process by which two DNA molecules are formed from one DNA molecule. In simple words, it’s like ‘duplication’ of a DNA molecule. The DNA molecule is copied whereby each of the new molecules contains a single strand of the original ‘parental’ DNA and one of the newly formed DNA strand (Weaver, 2005). The process occurs in a series that contains four steps; Initiation, Elongation, Termination and Proofreading/Correction.…

    The discovery of DNA began in the 1800s. The origin of DNA was discovered by Gregor Mendel the “Father of Genetics” in 1857 while he was performing an experiment of genetics with pea plants (Schwarzbuch, Smykal, Dostal, Jarkovska and Valova, 2014). Years few later, Johnann Friedrick Miescher began to follow Mendel studies and discovered the molecules of DNA. Moreover, the use of DNA in Forensic science did not receive a breakthrough until the 1950s. James Watson and Francis Crick solved the genetic puzzle and discovered the structure of DNA (Portin, 2014). James and Crick were the first to discover the structure of DNA after following the work of pioneers before them. They came to a ground-breaking conclusion about the structure of DNA in 1953 (Portin, 2014). In 1980s, the discovery of DNA testing…
