MODULE 2: GENETICS‚ VARIATION AND NATURAL SELECTION SPECIFIC OBJECTIVES & EXPLANATORY NOTES 1. Structure and Roles of Nucleic Acids 1.1 illustrate the structure of RNA and DNA using simple labelled diagrams; The genetic substance found in all organisms called DNA or deoxyribonucleic acid is a kind of nucleic acid. Nucleic acids consist of two long polymers of simpler units‚ called nucleotides; that are composed of three (3) main units as shown below: 1) A pentose sugar (deoxyribose

ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

by and ran a 9.58 second time (Greatest). When compared to Thomas Burke‚ the gold winner in Athens 1896 (Tom)‚ who had a time of 12 seconds even‚ Bolt seems to be dramatically faster. However‚ the rapid development of technology has created the separation in time. This is problematic as it causes the history books to forget about the immense talent and skill of those who came before. When placed in comparable terms Tom and other early modern era Olympians would be able to compete with Bolt. As

Crude Distillation Unit (Unit 1100) The purpose of the Crude Distillation Unit (CDU) is to produce a long residue‚ which is a feedstock of downstream RFCC unit‚ from a mixture of long residue and Oman Export Blend Crude (hereinafter referred to as Mixed Crude). CDU is designed to process 116‚400 BPSD of Mixed Crude‚ consists of 40‚000 BPSD of long residue and 76‚400 BPSD of Oman Export Blend Crude and is supplied from the Mina Al-Fahal refinery. CDU also produces LPG‚ naphtha‚ kerosene and gas

Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

DNA is a double helix molecule that contains information that is used to make up a person’s body. DNA controls every aspect of a person’s body from their eye and hair color‚ height‚ and other features. DNA’s specific and unique characteristic can be crucial when solving a crime. DNA can be used to convict a suspect or exonerate an innocent person. When DNA is found it is even more important that is handle properly to ensure proper identification and accuracy of testing. The evolution of DNA technology

Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding
