Experiment Four: Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction

You have to have enough carbs.” Find out if Janine is right. How does the nervous system use glucose? . Janine also said: “If you eat way too much protein and not enough carbs you can ruin your kidneys forever because of all the nitrogen you have to process breaking down the protein.” Find out if Janine is right about

DNA REPLICATION WHAT IS DNA? DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A)‚ Guanine (G)‚ Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose. THE PROCESS OF DNA REPLICATION How DNA replicates is quite a simple process. First‚ a DNA molecule is "unzipped". In other words‚ it

will finish off talking about PCR‚ and then we will discuss how it can be used. If we go back to the slide of the double stranded DNA‚ and if we take that to a high temperature‚ the two strands separate‚ you then add the primers‚ which interact with ? On the strand‚ synthesis takes place in the 5-3 direction‚ then you end up with 2 molecules identical to the DNA‚ and then you do another round‚ so it’s an exponential increase. There are different enzymes and polymerases‚ which come from bacteria

Chapter 7 Lab Exercise 7.1.1 Part of the distinction between LAN and WAN networks is ownership. Why is it impractical for an organization to own the entirety of a WAN? Why is it favorable for an organization to maintain ownership of the entirety of a LAN? Use your textbook and Internet research to compose your answer A) There are no limitations on WANs so they can be custom built for the size of the organization. For the purpose of organizational expansion. Exercise 7.1.2 Given the problems with

Running Head: DNA Testing DNA Testing CRJ 311 Forensics Timothy Knox November 4‚ 2012 Thesis DNA testing has become a major part of forensic science. It helps in so many areas of life. Catching criminals‚ freeing the innocent‚ determining paternity of children‚ amongst other things‚ are just a few ways DNA testing helps. It has a few cons like the financial burden of it. But in the end it is worth it. Without DNA there would be many offenders roaming the streets‚ while hundreds of innocents

Forensic DNA Evidence DNA has become one of the most accurate tools used in law enforcement in determining guilt or innocence. DNA is different in all people it is our “genetic blueprint.” DNA is so significant to law enforcement because DNA left at a crime scene can be collected and tested to see if there is a match. It is unique because it ensures accuracy and fairness. The initial use of DNA began in Britain in 1986; the FBI used it for the first time in the United States two years
