Chapter 4: Nucleic Acids and the RNA World 1. 4.1 – What is a Nucleic Acid? * Nucleic acids are made up of monomers called nucleotides * Three components of a nucleotide: 1. Phosphate group—attached to the 5’ carbon 2. Sugar – carbonyl group and several hydroxyl groups 3. Nitrogenous base * The prime (‘) symbols indicate the carbon being is part of the sugar—not attached to the nitrogenous base. * Four different nucleotides‚ each of which contains a different nitrogenous

Common Aspects of Acid Prehydrolysis and Steam Explosion for Pretreating Wood Hans E. Grethlein Michigan Biotechnology Institute‚ PO Box 27609‚ Lansing‚ Michigan 48909‚ USA & Alvin O. Converse Thayer School of Engineering‚ Dartmouth College‚ Hanover‚ New Hampshire 03755‚ USA Abstract The initial rate of hydrolysis using cellulase from Trichoderma reesei for various wood samples is directly proportional to the surface area available to the enzyme. Both dilute acid hydrolysis in a continuous

EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

one of two very similar pentose rings. Ribonucleic acids contain the sugar ribose. Deoxyribonucleic acids contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions. The Nitrogen-Containing Bases There are two types of bases found in nucleic acids. The purine bases have two nitrogen containing rings

experiment is to successfully perform a dehydration of 1-butanol and 2-butanol‚ also dehydrobromination of 1-bromobutane and 2-bromobutane to form the alkene products 1-butene‚ trans-2-butene‚ and cis-2-butene. The dehydration reactions react under and acid-catalysis which follows an E1 mechanism. It was found that dehydration of 1-butanol yielded 3.84% cis-2-butene‚ 81.83% trans-2-butene‚ and 14.33% 1-butene‚ while 2-butanol is unknown due to mechanical issues with the GC machine. For the dehydrobromination

CITRIC ACID IN A SOFT DRINK USING ACID/BASE TITRATION Copyright: Department of Chemistry‚ University of Idaho‚ Moscow‚ ID 83844-2343; 2007. INTRODUCTION The acid content of many foods and beverages contributes significantly to their taste. Soft drinks often contain varying quantities of several acids‚ which give sodas their tart flavor. In cola products‚ these acids are predominantly carbonic acid (from the carbonated water) and phosphoric acid. In sodas such as Squirt and 7-Up‚ the acids are
