'''Deoxyribonucleic acid ([[DNA]])''' is a very large biological [[molecule]] that is vital in providing information for the development and reproduction of living things. Every living organism has its own DNA sequence that is like a unique 'barcode' or 'fingerprint'. This inheritable variation in DNA is the most important factor driving evolutionary change over many generations. But, beyond these general characteristics, what "exactly" is DNA? What are the precise physical attributes of this molecule that make its role so centrally imposing in understanding [[life]]?


DNA is a long [[polymer]] of simple units called [[nucleotides]], held together by a [[sugar]] [[phosphate]] backbone. Attached to each sugar molecule is a molecule of one of four ''[[bases]]''; [[adenine]] (A), [[thymine]] (T), [[guanine]] (G) or [[cytosine]] (C), and the order of these bases on the DNA strand encodes information. In most organisms, DNA is a [[double-helix]] (or duplex molecule) consisting of two DNA strands coiled around each other, and held together by [[hydrogen bonds]] between bases. Because of the chemical nature of these bases, adenine always pairs with thymine and guanine always pairs with cytosine. This ''complementarity'' forms the basis of [[semi-conservative DNA replication]] &mdash; it makes it possible for DNA to be copied relatively simply, while accurately preserving its information content.  <font size=1>[[DNA|['''more...''']]]</font>

The International Olympic Committee was established in order to deal with the increasing problem of doping in the sports world and follows three fundamental principals, protecting the health of athletes, respecting medical and sports ethics, and ensuring equality for all athletes. The list of '''[[drugs banned from the Olympics]]''' is determined by the World Anti-Doping Agency. The banned substances and techniques fall into the following categories: androgenic agents, blood doping, peptide hormones, stimulants, diuretics, narcotics and cannabinoids. The use of alcohol (ethanol) is banned in selected sports only during actual competition.

Featured Article: Napoleon

Napoleon (Napoleon Bonaparte or, after 1804, Napoleon I, Emperor of the French) was a world historic figure and dictator of France from 1799 to 1814. He was the greatest general of his age--perhaps any age, with a sure command of battlefield tactics and campaign strategies, As a civil leader he played a major role in the French Revolution, then ended it when he became dictator in 1799 and Emperor of France in 1804 He modernized the French military, fiscal, political legal and religious systems. He fought an unending series of wars against Britain with a complex, ever-changing coalition of European nations on both sides. Refusing to compromise after his immense defeat in Russia in 1812, he was overwhelmed by a coalition of enemies and abdicated in 1814. In 1815 he returned from exile, took control of France, built a new army, and in 100 days almost succeeded--but was defeated at Waterloo and exiled to a remote island. His image and memory are central to French national identity, but he is despised by the British and Russians and is a controversial figure in Germany and elsewhere in Europe.

Rise to Power

Once the Revolution had begun, so many of the aristocratic officers turned against the Revolutionary government, or were exiled or executed, that a vacuum of senior leadership resulted. Promotions came very quickly now, and loyalty to the Revolution was as important as technical skill; Napoleon had both. His demerits were overlooked as he was twice reinstated, promoted, and allowed to collect his back pay. Paris knew him as an intellectual soldier deeply involved in politics. His first test of military genius came at Toulon in 1793, where the British had seized this key port. Napoleon, an acting Lieutenant-Colonel, used his artillery to force the British to abandon the city. He was immediately promoted by the Jacobin radicals under Robespierre to brigadier-general, joining the ranks of several brilliant young generals. He played a major role in defending Paris itself from counter-revolutionaries, and became the operational planner for the Army of Italy and planned two successful attacks in April 1794. He married Josephine (Rose de Beauharnais) in 1796, after falling violently in love with the older aristocratic widow.[1]
