of this lab was to compare the action of a catalyst (enzyme) under different environmental conditions. This was determined by performing a variety of different experiments. The first experiment was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme was present

gene pair). In humans‚ height‚ weight‚ and skin color are examples of polygenic inheritance‚ which does not follow a Mendelian pattern of inheritance. pleiotropy is the single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits. Mutation in this type of gene will simultaneously affect more than one trait. An example is phenylketonuria‚ a human disease caused by mutation(s) in a single gene that codes for the enzyme‚ phenylalanine hydroxylase. The disease is characterized

Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

EZH2 is an enzyme which adds methyl groups to the twenty seventh amino acid (Lysine) and is 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

For example: Mg + 2HCl Mg + H2SO4 MgCl2 + H2 MgSO4 + H2 I discovered from an A’ level text book (A-level Chemistry by Ramsden) that nitric acid doesn’t usually give hydrogen‚ but may do with magnesium if the acid is cold and dilute. The book didn’t say how dilute the acid had to be. Other products may include oxides of nitrogen. I know that some acids are weak and some are strong. A strong acid is one which ionises fully in solution to give hydrogen ions and‚ for example‚ chloride ions

a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia‚ 2012). Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular reactions. All proteins are made up of amino acids (Johnson‚ 2010). The purpose of this experiment is to determine whether peptide bonds are present in various food substances. The color violet will indicate the presence of
