The Role of DNA in Protein Synthesis DNA is found in the cells nucleus. It is part of the chromosome of the cell. DNA is the molecule that controls the making of protein. Protein is used for the growth of cells and organisms and also for the repair of cells. Protein is also used as an enzyme to speed up reactions in the body. Because of this DNA is able to control the whole organism. With out DNA and its ability to make protein the cells and eventually the whole organism would die

Synthesis of 1-Bromobutane from 1-Butanol Reference: Discovering Organic Chemistry in the Laboratory; John R. Ganson Ph. D‚ Revised 2011 by Alfredo Mellace Ph. D www.Aldrich.com Purpose: To synthesize 1-bromobutane from 1-butanol via SN2 reaction. Alcohols are converted into the alkyl halides adding an aqueous solution sodium bromide. The sulfuric acid acts as a catalyst in converting the OH functional group of butanol‚ to a better leaving group. In order for this reaction to synthesis 1-Bromobutane

It is so crucial because it allows for the understanding of how molecules interact in order to create new products. Generally speaking‚ multistep synthesis could be useful in a practical application such as pharmaceutical chemistry. Synthesizing aspirin is a common example of a multistep synthesis reaction. Aspirin is typically taken as a painkiller or as a reducing-agent for fevers. In order to synthesize this product‚ the reactants salicylic acid and acetic anhydride

Creating a Sustainable Environment Every day our environment is ravaged by emissions‚ littered on by billions of people‚ and carelessly treated with unlimited sources. Environmentalists like Bill Mckibben‚ scholar at Middle berry College and author of the article “The Challenge to Environmentalism‚” believe that “the relationship between people and the natural world has been largely taken for granted for most of human history” (500). Although environmentalism to some people mean driving less‚ establishing

Kyrie Staab Mrs. Wieseman Hon. English 10 Dec. 18‚ 2012 Is Our American Dream Fading Away? The attainability and very existence of the American dream has been debated for many years. As the economy‚ politics‚ and social standings change‚ so do the expectations and beliefs about what the American dream should be and how one should go about achieving it. The main question involved in this debate is not so much whether the dream is alive or dead‚ but whether America’s dream can ever be fully realized

Of all the elusive‚ seductive concepts shared by the disciplines of literary studies‚ art‚ and psychology‚ genius is among the most scoffed at‚ the least understood. To hear‚ as I have heard‚ a literature professor say that he "doesn’t believe in genius‚" as if millions of people haven’t attained I.Q. scores in excess of 140‚ or as if anyone‚ if he or she only worked vigorously enough‚ could pen a single work comparable to The Canterbury Tales or Paradise Lost or The Rape of the Lock‚ is to know
