a physicist who led the King’s College London team which worked on the structure of DNA) gave Franklin the A form and Wilkins the B form‚ assigning them each the task of elucidating their molecular structure. Wilkins and Franklin used X-ray crystallography as a technique to set out their experiment. The steps to this technique are simple‚ you just need to expose a crystal to X-ray in order to produce a diffraction pattern. Once you have a pure enough diffraction patterns it is possible to then reconstruct

DNA Lab Report SungYong Jang What is DNA? What do the letters stand for? What is it composed of? Where is it found? What is it shaped like? Answer in full sentences. It is the genetic material that can be passed on from parent to offspring DNA --> Deoxyribonucleic acid It composed of Deoxyribose (5 carbon sugar)‚ a phosphate and a Nitrogonous base (the 4 N-bases are Guanine‚ Cytosine‚ Adenine and Thymine) It is a double helix (looks like

Linus Pauling is said to be one of the most significant scientists to have ever lived. Given Pauling’s wide array of accomplishments‚ ranging from winning the nobel peace prize to solving complex atomic structures‚ it is easy to see why he has earned the respect of so many in the scientific community. Pauling was born on February 28‚ 1901 in Portland‚ Oregon. Even as a young boy he took interest in science; a friend introduced him to a toy chemistry set‚ and instantly young Linus was hooked and began

Living organisms are composed of part water and part chemicals. The chemicals that help make up life are constructed mainly of carbon. A compound that has carbon in its composition is called an organic compound. Organic compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size

When attempting to define what constitutes discovery in the realm of science‚ it helps to determine the motivations for doing so. In the case of the discovery of the double helix‚ for example‚ the most prevalent motivation is credit. With this as an incentive‚ it makes sense that someone might attempt to define discovery within a relatively constricting set of parameters. If you were to look at it from a more philosophical standpoint however‚ you might find discovery a lot more difficult to define
