How To Write A Pglo Lab Report

This lab is about moving genes from one thing to another using plasmids. Plasmid has the ability to replicate, so it replicates independently, and separately from the chromosomal DNA. Plasmid are one or more small piece of DNA and they enter cells as a double strand DNA. When they enter the cell as a doubke strand they do not invade he chromosomal DNA. We will also transform bacteria into GFP which is mainly from the jelly fish Aequorea Victoria. The GFP causes the the jelly fish to fluorescent and glow in the dark. After the transformation, bacteria starts to make the GFP which causes them to glow a green color under a ultraviolet light.

The pGLO plasmid is engineered to express green fluorescent protein (GFP) in the presence of the sugar arabinose as well as the ampicillin resistance gene β-lactamase (bla) (Brown, 2011). Original E. coli HB101 do not have ampicillin resistance or the GFP gene allowing them to glow under UV light. In this experiment, we transformed E. coli HB101 with the pGLO plasmid by heat shock to make the bacterial cells competent, allowing the plasmid to enter the cell (Brown, 2011). The mixture of bacteria with pGLO plasmid were given recovery time after heat shock, then spread on LB/amp and LB/amp/ara agar plates. The bacteria mixture with no plasmid added were spread on LB and LB/amp agar plates and all four plates were incubated at 37°C for

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

Control plasmids lux and pUC18 were introduced into E. Coli through a process of transformation.

The purpose of the PGLO lab was to be able to perform a procedure known as a genetic transformation. We used a procedure to transform bacteria with the gene that codes for a Green Fluorescent Protein (GFP). The actual source of the GFP gene that we used in this complicated experiment is the bioluminescent jellyfish Aequorea victoria. This protein causes the jellyfish to glow under a UV light that was provided in the dark. After the transformation procedure, the bacteria showed their newly acquired gene from a jellyfish and produced the fluorescent protein, which as a result, causes it to glow. If the bacteria glowed in the dark, that was the initial sign that the experiment was successful.

The plasmid pGLO contains an antibiotic-resistance gene, ampR, and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli, so if E. coli, so if E. coli cells contain the ampicillin-resistance gene, the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus, transformed E. coli cells containing ampicillin-resistance plasmids can easily be selected simply growing the bacteria in the presence of ampicillin-only the transformed cells survive. The ara control region regulates GFP expression by the addition of arabinose, so the GFP gene can be turned on and

In the pGLO Bacterial Transformation lab, Escherichia coli is transformed with a gene encoding green fluorescent protein by inserting a plasmid containing the GFP gene, beta-lactamase, and arabinose into the bacterium. Successfully transformed bacteria will grow in the presence of ampicillin and glow a bright green color under ultraviolet light. The sugar arabinose is responsible for switching on the GFP gene in the transformed cells, without it, the gene will not be expressed.

The pGLO plasmid will transform the E. coli bacteria with a gene called GFP that codes for the Green Fluorescent Protein in the genetic code. GFP was discovered in the jellyfish, Aequorea victoria as a green fluorescent light emitted from the jellyfish. It was typically seen in the dark upon its activation and since then has been used in studies relating to genetic transformation. (Chalfie and Tu 1994) The majority of the studies test the many different factors that are required in the transformation of pGLO which will determine the functionality of GFP in the E.coli bacterium. The first experiment in transforming GFP and E. coli was completed in 1994 by Chalfie and was further refined the same year. The experiment proved the importance of using restriction enzymes, and DNA ligase in the process of transforming GFP to identify arabinose as the primary activator, and to identify the ampicillin

The goal of this experiment was to investigate genetic transformation of E.coli through the reaction of organism to the vector pGLO plasmid. As mentioned, the pGLO plasmid contains genes coding for resistance to ampicillin (amp), and genes coding for production of the green fluorescent protein (GFP) which glows under UV light in the presence of arabinose (ara),which serves as a reporter gene. This green fluorescent

Scientists can study and manipulate genes by using precisely engineered plasmids, According to ADDGENE, a nonprofit plasmid repository, plasmids “have become possibly the most ubiquitous tools in the molecular biologist’s toolbox” (“What Is a Plasmid?”). In this experiment, we will use pGLO to genetically transform the bacteria E. coli. pGLO is a genetically engineered plasmid that carries the reporter genes for both green fluorescent proteins (GFP) and the ampicillin resistance. GFP, a protein typically found in the bioluminescent jellyfish Aequorea victoria, exhibits a bright green fluorescence in the presence of blue to UV wavelengths (Mecham); the protein absorbs UV light from the sun and emits it as a lower energy green light, exemplifying the second law of

Genetic transformation occurs when genes are inserted into another gene to change the organism’s trait (Weedman2016). In this experiment, we proceeded to transform the E. coli bacteria with a gene that contained green fluorescent protein. The green fluorescent protein is used in experiments because it beams a green color under a UV light (Chalfie2008). Typically, it is used to mark the expression of genes, which is why it serves as the symbol for all gene expressions (Tsien1998). In the experiment, we will be using pGLO as the organisms that will transmit the disease, otherwise known as a vector. The pGLO in the experiment

DNA, Deoxyribonucleic Acid, is the basic structure for all life, it is the blueprint, the instruction manual, on how to build a living organism. DNA is made up of four nitrogen bases, adenine, thymine, cytosine, and guanine which are connected by sugar-phosphate bonds. Through a process called Protein Synthesis, the nitrogen bases are the code for the creation of amino acids. Essentially, DNA makes amino acids, amino acids make proteins, proteins make organisms. This process has been taking place for much longer than scientists have been able to document. Those scientists are called geneticists and their field is genetics.

DNA is a long curved structure, made up of pairs of four specific bases: adenine, guanine, cytosine, and thymine, is the repository of a code from which all of our cells are made. The code is made up of base pairs which look like the

All living organisms, from amoebas to humans, have a molecular code called DNA in their cells, which instruct the activities that keep the organism alive. DNA is made up of long, twisted strands of four molecular “letters” (A, T, G, and C), which pair up according to their complementary base pairs, and their order determines how proteins — the vital molecules that perform all the major tasks in our cells — are made. (Refer to Diagram 1 to help sum up the concept.)

Deoxyribonucleic (DNA) is the molecule that hold the genetic information of living things. In our body every cell contains about 2 meters of DNA. DNA is copied every time a cell divides. Deoxyribonucleic (DNA) is made up of two polynucleotide strands. Polynucleotide strands twist around each other, forming a shape that looks like a ladder called a double helix. The two polynucleotide strands run antiaparallel to each other with nitrogenous bases this means that the stands run in opposite directions, parallel to one another. The DNA molecule consists of two backbones chains of sugars and phosphate groups. The organic bases held together by hydrogen bonds. Although bases bonded together are termed paired
