Linus Pauling

Franklin, had gotten X-ray images of DNA that suggested a helical, spiral shape (“The Francis Crick Papers,” 2013). To create their models, Watson and Crick adopted the model-building technique, developed by American chemist Linus Pauling. To determine the structure of molecules, Pauling used pieces, shaped according to the known characteristics of the atom it represented. Then, he manipulated the pieces to figure out the most logical way for them to fit together (Aaseng, 1984, p.…

Our lives and the lives of those before us, have been unknowingly (or knowingly) shaped by elements. In The Disappearing Spoon, the author Sam Kean, discusses the wonderful world of the periodic table in depth. Within the first nine chapters of the novel, Kean explains the importance of location on the table, origin and discovery of each element, and its impact on other aspects of human life. Through various tales, the table is pulled apart and analyzed in an ingenious way. To a reader, it is…

A Triple Berry Smoothie, which is made up of one cup each of strawberries, raspberries, blackberries, and two table spoons of Ovaltine Chocolate Molt contains such essential nutrients as protein, fat, fiber, sugar, and vitamins. Essential nutrients, hence their “essential” moniker, are required to be consumed on a daily basis in order to live. A key essential nutrient present in the Tripe Berry Smoothie is Vitamin C. One cup of raspberries contains 53% of the daily requirement for Vitamin C, one…

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…

I was born on February 28, 2001 in Kilmarnock, Virginia. I have a younger step-sister, Jolie and a little sister, Keira. When I was born I had a single mom working in Williamsburg, while my grandparents took care of me at home and an immature father cleaning pools in California. *Insert parent interview! However, my birth was not the only exciting thing to occur on this day. On February 28, in 1944 test pilot Reitsch pitched a suicide squad to Hitler, in 1953 Watson and Crick discovered chemical…

Bias and prejudice have resonated in cultures throughout time. Prejudice begins as a perceived opinion or idea without evidence to support it; eventually, it evolves to a greater concern: racism. In the United States alone, nearly one thousand hate groups have taken root and amplified the issue of racism in the U. S. Major events that negatively depict a minority can undermine progress towards equality. This is discussed in an interview with Professor Abu-Lughod where she explains how Muslim…

The book I read for my Biology book report was, The Double Helix, A Personal Account of the Discovery of the Structure of DNA an autobiography written by James D. Watson. It was released in 1968 and was published by Atheneum Press (US), Weidenfeld & Nicolson (UK) and is 226 pages. As the title suggests, the book is Dr. Watson’s personal account of the groundbreaking discovery of the structure of DNA. Biologists already knew that genes were the material responsible for traits getting passed from…

Paraphrase 1 Citrus sinensis, Commonly known as Orange,Is ¼ Pomelo and ¾ Mandarin as it is a mixed breed of the two fruits.Approximately in the year of 2500 B.C. in southeast Asia, northeastern India and southern China where they were firstly made.From India the romans delivered some fresh orange trees to Rome in 1st century A.D. as well as people from north Africa started growing them too.In the year of 1493 in Spain’s Canary Islands to Haiti by the adventurer named Christopher Columbus also…

In The 1940’s Have you ever wondered how technology and science got so advanced? Many different items that we use today started from something that may seem small, such as, medicine, cell phones, and even irregular things like guns and bombs. Linus Pauling once said, “Science is the search for truth. It is not a game in which one tries to beat others.” While not a game, it is fought like one. Scientists have developed weapons and strategies to progress their performance on the battlefield.…

The fight to discover the structure of deoxyribonucleic acid continues in James Watson’s The Double Helix. Linus Pauling thought he had discovered the structure of the acid, but in fact he had come with an incorrect structure that did not represent an acid at all. The basis of Pauling’s model consisted of a three-chain helix in which the sugar-phosphate backbone resided in the center of the molecule. The phosphate groups in this theoretical structure were not ionized. Instead, each phosphate…
