DNA model of the structure resembled a twisted rope ladder. They proposed that the DNA molecule consisted of two spirally wound‚ helical chains. Rosalind Franklin (1920–1958) Franklin had established herself as a world expert in the structure of graphite and other carbon compounds. Rosalind Franklin had discovered that DNA could crystallize into two different forms‚ an A form and a B form. John Randall (was a physicist who led the King’s College London team which worked on the structure of DNA) gave

CHAPTER 4 AIRCRAFT BASIC CONSTRUCTION INTRODUCTION Naval aircraft are built to meet certain specified requirements. These requirements must be selected so they can be built into one aircraft. It is not possible for one aircraft to possess all characteristics; just as it isn’t possible for an aircraft to have the comfort of a passenger transport and the maneuverability of a fighter. The type and class of the aircraft determine how strong it must be built. A Navy fighter must be fast‚ maneuverable

524 SILICON CARBIDE Vol. 22 SILICON CARBIDE 1. Introduction Silicon carbide [409-21-2] (SiC) is a technologically important material that is one of the small number of unusual materials that were first created synthetically and then subsequently discovered in nature. Silicon carbide was first observed in its natural form in 1905 by the Nobel-prize-winning chemist Henri Moissan‚ who discovered it in the meteor that created the Diablo Canyon in Arizona. The transparent mineral‚ now known as

Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat
