    The Phenomenon that is Genetic Transformation Matt Kimmel November 17‚ 2011 Bio 121-012 Introduction Genetic transformation is when the genetic makeup of an organism is altered by it receiving external genetic material (Barnhart and Hopper‚ 2011). Bacterial transformation was first seen during an experiment by Fredric Griffith in 1928. In the experiment there were two strains of bacteria‚ a virulent strain‚ and non-virulent strain. Virulent simply means disease causing‚ and therefore non-virulent

    Introduction In this week’s laboratory period students had the opportunity to perform a common procedure preformed by many if not all microbiologists known as genetic transformation. Genetic transformation is the ability to move DNA into an organism and thereby altering its genotypic and genetic makeup (2). Genetic transformation has shown to have a wide variety of uses in many scientific studies. In agriculture‚ gene coding for traits such as frost‚ pest‚ or spoilage resistance have been genetically

    Optimal Growth Conditions and Generation Time for E. coli Introduction The goals of these exercises were to determine the optimal growing condition and the generation time of E. coli. Materials and Methods Please refer to the lab manual for a complete list of materials. To determine the optimal growth condition for E. coli‚ we had to test the environmental factors that could affect the growth. We tested the relative growth of E. coli in the presence and in the absence of oxygen. The results

    166-0003EDU Week 7: pGLO Transformation Introduction to Transformation In this lab you will perform a procedure known as genetic transformation. Remember that a gene is a piece of DNA which provides the instructions for making (codes for) a protein. This protein gives an organism a particular trait. Genetic transformation literally means change caused by genes‚ and involves the insertion of a gene into an organism in order to change the organism’s trait. Genetic transformation is used in many areas

    Miguel Felix pGLO Transformation Mr. Betz AP Biology 14 December 2012 Abstract The purpose of this experiment is to determine the effects of the addition of a plasmid to a bacterial cell. The bacteria E. Coli was separated into two groups: one where the pGLO plasmid was added to the bacteria‚ which contains the genes of fluorescence and resistance to antibiotics‚ and the other lacking the plasmid. The two groups then placed in agar plates simulating different environments: the bacteria lacking

    Connor Lauffenburger 3/17/13 pGlo Transformation Lab Report I Introduction The purpose of this experiment was to show the genetic transformation of E. coli bacteria with a plasmid that codes for Green Fluorescent Protein (GFP) and contains a gene regulatory system that confers ampicillin resistance. A plasmid is a genetic structure in a cell that can replicate independently of chromosomes. In this lab‚ the Green Fluorescent Protein‚ which is typically found in the bioluminescent jellyfish Aequorea

    The Figure 4.20 shows the profile growth of Escherichia coli type K-12 which was cultured in 20 g/L of glycerol treated with supplements from a carbon source under anaerobic condition and the medium supplemented with 10 g/L of trypton. About 10% working volume of inoculums were added to the medium for the profile growth process. The effects on growth curves of strains of Escherichia coli were investigated by measuring the concentration of succinic acid produced and its optical density by using HPLC

    Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media‚ it could be seen that the

    Transformation of E. coli with your unknown plasmid Learning Goals: Insert your uncut unknown plasmid into chemically competent DH-5 E.coli cells and use antibiotic resistance to confirm the success of the transformation. You should familiarize yourself with the various methods of transformation and the advantages/disadvantages of each type. You should also understand how heat shock transformation works and how chemically competent cells make this type of transformation possible. For this transformation
