Genetic engineering is changing the DNA code to express different traits. A plasmid is a circular piece of DNA that contains important genetic information. Recombinant DNA is the product after inserting your desired genes. The genes we hoped to insert in the pGLO lab were the GFP gene and the ampicillin resistance gene. GFP was needed so that we would tell if the ampicillin resistance gene had been properly placed when the bacteria glowed under a UV light. The purpose of this lab was to perform a procedure known as genetic transformation which allowed us to genetically engineer E. Coli to be ampicillin resistance. Before the lab we expected that lysogeny broth and minus DNA will have growth but no glow. The lysogeny broth, ampicillin, and …show more content…

Meanwhile, on our LB/amp plus DNA petri dish we had a lawn of bacteria and the color was almost clear. Our results for this petri dish mean that the bacteria was not killed by the ampicillin. Next, in the LB/amp minus DNA petri dish we observed very minimal amounts of growth. These results mean that we correctly followed the procedures because this petri dish was not supposed to have growth due to the ampicillin. Our last petri dish was minus DNA and lysogeny broth, in this petri dish we saw 7 colonies of bacteria and there were a light yellow color. These results mean that we didn’t infect that petri dish with ampicillin from the pipette. Our expectations were both unsupported and confirmed. For example, our minus DNA and lysogeny broth had bacteria growth while our LB/amp/ara plus DNA dish had no growth and did not glow. Some problems that might have occurred in the lab is that we either put too much ampicillin in our LB/amp/ara dish or we could have had all plasma and no bacteria. Something that was difficult for me personally was the disposing of the pipette tips when switching from different substances and pipetting the right amount. These difficulties might have caused me to make mistakes on the amount needed to pipette or the type of substance. Overall, next time I would have made sure to pay closer attention to the pipetting portion of the procedure. Furthermore, we could extend this experiment by trying different kinds of

chinesis. A construct of R751::Tn4351 (the physical map of R751::Tn4351 and restriction sites are shown in fig. 7) was selected for introduction into F. chinesis to discover if the introduction and insertion of the vector R751 and the transposition of T4351 into the F. chinesis chromosome by a triparental mating occurred. One parent was E. coli GJ342 which carried a helper plasmid, the second parent was E. coli HB101 which contained R751::Tn4351 and the third parent was the F. chinesis target strain. 189 colonies were isolated on LB agar plates which in passage in fresh media were able to grow in 200µgml-1 erythromycin.

The Mut section is expected to have no growth as mutants require the amino acids leucine and valine to grow which is not provided in the minimal medium. Results Figure 2. Testing of mutant mixed with DNA, mutant bacteria and DNA on LB medium Growth was observed on the Transformed (Trsf) section and the Mutant (Mut) section but not on the DNA section. Due to human errors, the photo of our experiment was lost, but we have obtained similar results as from group1.1 and their photo is presented.

Aseptic technique was initiated at the beginning of this experiment by cleaning the work surface with disinfected wipes. Personal protectives equipment was also worn. The material utilized in this experiment was: S. epidermidis culture broth, sterile cotton swab, streak plate, forceps in 70% alcohol, a lit tea light, and the three antibiotic disks (novobiocin, gentamicin, penicillin). The first step, I divided a plate into three quadrants and labelled them with the different antibiotic names. Using the lit tea light, like a bursen burner, I flamed the mouth of the S. epidermidis culture.

Unknown Bacteria

In the laboratory, identification of an unknown bacterium is often necessary. In the lab, a random sample consisting of three different bacteria was selected. The sample contained one gram-positive, one gram-negative paracolon, and one gram-negative coliform. The purpose of the experiment is to identify each of the three species that the mixture contained. After receiving an unknown mixture, the sample was streaked for isolation onto TSA, blood agar, and MacConkey plates.

For thousands of years, nature and human manipulation has continually shaped the variety of foods we consume as well as the processes used to control their production. These foods and ingredients are genetically different from what they once were. The science behind modern food processing and modification uses methods created by biotechnology. Generally, genetic modification is the manipulation of an organism’s genome using biotechnological processes and technologies. It involves the removal, addition, or modification of an organism’s genes in order to create a new organism.

The putrid smell of Escherichia coli is one that is immediately identifiable to the few lucky individuals who recognize its scent. It is also an aroma with which I became intimately sensitive to as I shuttled petri dishes of the bacterium in and out of an incubator. While my classmates shied away from the task of handling the pungent bacteria used in our recombinant DNA experiments, I took to the task eagerly, anything that would take me one step closer to my goal of researching. I had the opportunity to learn about lab techniques and cutting edge biology concepts the summer before my junior year, in an extracurricular biotechnology class at Northwestern University’s Center for Talent Development. The class, a three week crash course in the

Disadvantages Of Enviropig

Introduction: Genetically modified organisms can be defined as organisms in which the DNA has been changed in a way that does not occur naturally by any reproduction procedure. The enviropig is just one of many organisms that they did experiments on to modify it to have specific (needed) outcomes. The reason for genetic modification is to be able to change a product or organism so that it deliver desirable traits. The enviropig was created to solve the problem of pigs not being able to absorb enough phosphorous from their diet, which then in its turn contributes to the larger factor of pollution.

Pro Genetic Engineering Essay

1719 Words | 7 Pages

Genetic engineering is the use of new technology to alter the genetic material and DNA to change the instruction codes thus changing the characteristics of the cell in hopes that the organism will be more fit to survive. Surprisingly, people spend their lives fighting over the ethics of this issue. Some feel that it is the future of medicine, where others think it is a sin to practice such risky technology with something as valuable as a life. In reality, the solution may be highly simple. Genetic engineering should be available because it allows scientists opportunities to further advance science, including empowering prospective parents to give their children a healthy life.

Biochemical tests are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Bacterial physiology differs from one species to the other. These differences in carbohydrate metabolism, protein metabolism, fat metabolism, production of certain enzymes and ability to utilize a particular compound help them to be identified by the biochemical tests. Gram’s stain was originally devised by histologist Hans Christian Gram in 1884. Gram-positive bacteria stain purple, while Gram-negative bacteria stain pink when subjected to Gram staining.
