Chapter 15 The chromosomal basis of inheritance Key ideas: 1) Mendelian Inheritance has its physical basis in the behavior of chromosomes during sexual life-cycle. 2) Morgan traced a gene to a specific chromosome. 3) Linked genes tend to be inherited together because they are located on the same gene. 4) Independent assortment of chromosomes and crossing over produce genetic recombinants. 5) Geneticists use recombination data to map a chromosome’s genetic locus. 1900 Biology finally

Purpose: To find how pH and temperature levels affect the enzyme Background: Enzymes are a type of protein vital to sustaining life‚ it works with vitamins and minerals as a biological catalyst‚ which lowers the activation energy for a reaction to occur. Each individual type of enzyme does a specific job‚ and they do not die‚ they are reused. For example‚ catalase is an enzyme found in almost all living cells that will break down hydrogen peroxide and turn it into water and oxygen. The

____________________ Immobilizing an enzyme provides various analytical benefits‚ and can be done in a myriad of ways‚ with the most common being entrapment. For this study peroxidase (from horseradish)‚ an enzyme that catalyzes the cleavage of hydrogen peroxide into water‚ was entrapped within a polyacrylamide gel matrix. The gel matrix was formed by the addition of methylene bis-acrylamide (a cross linking agent) to acrylamide. The immobilized enzyme was then tested via spectrophotometric assay

Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function of the enzyme catalase

Introduction: Purpose: The Purpose of this experiment is to find the width of a piece of hair using diffraction pattern created by a thin film. Hypothesis: If the hair is human it will have a width of 10-4m. Procedure: 1. Place two pieces of glass flat against each other. 2. Obtain a piece of long hair‚ most likely from one group member’s head. 3. Place the hair between the sheets of glass on one edge. 4. Place a rubber band around the pieces of glass on the side opposite
