’Neil 2002). The particular conditions that had to exist for this to apply were that the population had no mutation‚ had no natural selection‚ was a large population‚ had only random mating‚ and had no migration. For the cases to follow later in the lab‚ Cases 1 and 2 exemplify Hardy-Weinberg conditions. All of the others either have selection or not enough members in the population‚ which will be the most-closely observed

Isolation‚ Expression and Cloning of Lactate Dehydrogenase Gene from Lactobacillus bulgaricus Lactobacillus bulgaricus is used for industrial production of yogurt mainly because of his fermentative capability. In this experiment‚ the gene encoding the enzyme lactate dehydrogenase [ldhA] from the bactaria was isolated and cloned. The expressed ldhA gene was inserted into pET28b plasmid vector. The resulting recombinant pET28b-LdhA expression vector was then transformed after introduction into E.

Raquel Johnson October 19‚ 2014 Solids: Recrystallization and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

Our main goal was to test organisms’ resistance and susceptibility to bacteria‚ and whether the cell wall of bacteria exposed the membrane to pathogen or protect it from pathogens. I thought P. aeruginosa was gram-positive and therefore it would be susceptible. That was my hypothesis.We divided antiseptic agar plate into quadrants and divided antibiotics agar plate into six areas. We wrote the organisms’ name‚ date‚ and the temperature on the bottom of the agar plates. For antiseptic‚ our group used

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

Frozen Yogurt In 1994‚ General Mills Incorporated‚ a $6 billion consumer goods company‚ acquired Colombo Frozen Yogurt. General Mills Inc. (GMI) believed they could add Colombo frozen yogurt to their existing product lineup to increase net sales with little addition in marketing cost. Frozen yogurt is sold through two distinct segments – independent shops and impulse locations such as cafeterias‚ colleges‚ and buffets. Frozen yogurt is the main business for the shops whereas yogurt is incremental

2012-11-21 Staphylococcus aureus is the most pathogenic for humans and Staphylococcus epidermidis is part of the normal flora and is of low pathogenicity. Staphylococcus epidermidis and Staphylococcus aureus are two medically important species of bacteria. A culture from the nose and throat was taken to perform whether or not Staphylococcus epidermidis or Staphylococcus aureus were detected. Test were performed to determine which Stpahylococci was present and the results of the test indicated that
