Unknown Lab Report #1 Unknown #1 April 25‚ 2012 Microbiology Spring 2012 MCB2010C Unknown #1 Introduction Identity of a microorganism has proven to be very significant. Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods

Morgan Kimmerle Monday Lab Dr. McCorkell Abstract The purpose of this study was to cross and analyze the reciprocal crosses of wild flies and mutant flies. In this lab Drosophila melanogaster commonly known as fruit flies were used to understand some important genetic principles that were once proposed by Gregor Mendel. Mutant traits can be autosomal dominant‚ autosomal recessive traits‚ or even sex-linked dominant and sex-linked recessive. F1 and F2 generations were obtained by performing

Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The chemical reaction is shown as 2H2O2 = 2H2O + O2 (Keilin and Hartree 397). The reaction involves primarily the adsorption of hydrogen peroxide at the catalase surface. The decomposition of hydrogen peroxide by catalase is regarded as involving

purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows

encoded by EZH2‚ the EZH2 gene encodes part of the Polycomb group which make protein complexes that help to maintain genes transcriptional repressive state over successive cell generations. http://www.ncbi.nlm.nih.gov/gene/2146 Throughout this lab report template DNA that contains the gene EZH2 was provided‚ this will be amplified by a PCR and cloned into a vector. This Polycomb group proteins help maintain the cell identity during progress through chromatin

conditions. The scope of this experiment includes Metabolic processes‚ such as cellular respiration‚ and it poisonous byproduct hydrogen peroxide. The methodology includes procedures; multiple variables were tested in specific concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures that are neither freezing nor boiling‚ catalase performs well in lower concentrations than the substrate

To begin this test‚ 3 water baths were set up. One bath was cooled to 0 degrees celsius‚ one was heated to 37 degrees celsius‚ and one was boiled to 100 degrees celsius. 1 of the four test tubes containing 2 ml of 100 units/ml catalase was put in to each of the three water baths‚ one at a time. While the tubes sat in the baths‚ the 4 H2O2 vials were prepared and the depth of the H2O2 was recorded. After the 0 degree celsius test tube incubated in it’s bath‚ it was taken

Purpose The purpose of this laboratory is three fold: 1. Familiarize the student with the concept and meaning of pH 2. Provide the student experience in measuring pH a. pH testing paper 3. Test the student’s hypothesis as it related to the pH of common solutions Hypothesis The pH of the tested solutions will be in the order of the following according to a pH scale: 1. Lime juice 2. Orange juice 3. Soda 4. Iced Tea 5. Milk 6. Water 7. Soapy water Material Required To facilitate
