The Genetic Transformation of Escherichia coli bacteria cells with pGLO

Introduction According to the Life 102: Attributes of Living Systems Lab Manual, a genetic transformation takes place when a cell displays characteristics of another piece of DNA, which has usually originated from another organism (Weedman, 2014). This area of science provides researchers with the ability to solve numerous real-world problems, which leads to advances in many areas of science including gene therapy and various agriculture practices. For example, a recent study wanted to find the best way to eliminate threats of insects to crops in order to increase food production (Sharma et al. 2004). By using genetic transformation, the experimenters in this study were able to genetically alter crops so that they would be resistant to most common threats (Sharma et al. 2004). As the example proved, genetic transformation is a highly utilized tool that is continually advancing and improving the world around us. …show more content…
In order for the glowing to take place, arabinose must be present. The vector of this transformation will be pGLO, which contains GFP and a gene for resistance to ampicillin. The ampicillin is necessary to the experiment in order to see transformed cells (Weedman, 2014). The goal of this experiment is to see whether or not Escherichia coli will undergo genetic transformation with pGLO. Experiments similar this one are important because they help researchers to better understand how bacteria behaves. This understanding allows researchers to eventually create better-suited antibiotic medicines in order to protect individuals from their harmful effects (Weedman,

centrifuge tubes were individually labeled –pGLO and +pGLO and then placed into a foam tube rack. Each tube was then opened and given approximately 250 µL of the transformation solution (calcium chloride), through the use of a micropipetter (with a fresh tip for each). Subsequently both tubes were closed and placed directly in a tub of ice. A single colony of bacteria was then picked up from the starter plate by a sterile loop and placed in the +pGLO tube. The loop was twirled in the transformation…

coli colonies you initially observed? Explain your predictions. Plates 3 and 4 should contain bacteria that are most like the original non-transformed E. coli colonies. This is because these plates serve as control plates. They do not contain the pGLO plasmid that causes genetic mutations or transformations. Plate 3 should not contain any bacteria because it has ampicillin, which prevents bacteria growth, but plate 4 should contain bacteria because it does not contain ampicillin. 2. If there…

First, you need to label 2 micro test tubes +pGLO and -pGLO. This needs to also have your groups initials or names if you are doing a class experiment. If you are doing a lab experiment for work, you should put…

Pglo Lab Report

Purpose The overall purpose of the pGLO lab was to transform E. Coli bacteria by adding materials such as luria broth, ampicillin, plasmid, and transformation solution. Transformation is a process in which one strain of bacteria is changed by a gene or multiple genes from another strain of bacteria. Procedures The first thing done for this lab was prepping the plates. Students labelled the plates, and then teachers put in agar agar in each plate, adding either pGLO plasmid, ampicillin, or arabinose…

Transformation Lab Report Introduction Transformation is the transfers of virulence from one cell to another, through the transferring of genetic material. It was originally postulated in 1928 through the works of Federick Griffith, a British microbiologist. Griffith observed that the mutant form, non-virulent form, of the bacteria Streptococcus Pnumoniae could be transformed into the normal, virulent form, when injected into mice along with heat killed normal forms. He concluded that somehow…

The protein used in process of transformation was green fluorescent protein. Two tubes were labeled “+pGlo” and “-pGlo” and 250 μl of CaCl was added and tubes were placed on ice. I used a sterile loop and extracted 3 large circular colonies of E. coli then swirled it into the +pGlo tube and repeated this process for –pGlo tube. Under UV light both tubes displayed no color difference. The tubes were placed on ice for 10 minutes then heat shocked at 42 ˚C for exactly 50 seconds in order for transformation…

Transforming E. Coli Bacteria with the Gene GFP (green fluorescent protein) By Using pGLO As a Vector Introduction: Genetic transformation is the alteration of a cell by taking DNA from another organism and expressing those new characteristics from the organism of which it took the DNA from (Julie Carnagie and Leonard C. Bruno 2006). The cells that are able to take up DNA from other organisms are known as competent. This genetic transformation is used for many different things, from making medicines…

We inserted a gene into the bacterium E. coli. Gene being a piece of DNA which provides the instructions for making a protein. The main chemical components used in this lab were calcium chloride, E. coli bacterium, a broth (made up of carbohydrates, amino acids, vitamins, nucleotides, and salts that allow bacteria to grow), pGLO plasmid (contains arabinose operon that turns on when the arabinose sugar is present, GFP that glows green in fluorescent light, bla that provides 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…
