their association with many human illnesses‚ microbes are also responsible for many beneficial processes such as industrial fermentation (e.g. the production of alcohol and dairy products)‚ antibiotic production and as vehicles for cloning in higher organisms such as plants. Scientists have also exploited their knowledge of microbes to produce biotechnologically important enzymes such as Taq polymerase‚ reporter genes for use in other genetic systems and novel molecular biology techniques such as the

Open Reading Frames * (ORFs) are regions with no stop codons. All genes reside in long open reading frames * Note that stop codons in other reading frames have no effect on the gene. * Can be searched in the genome sequence. Valid only for prokaryotes and lower eukaryotes. Protein Sequencing vs. DNA sequencing * We compare protein sequences‚ not DNA‚ because protein is more conserved in evolution than DNA * The organism’s survival depends on the protein being

State the principle of triple beam balance A beam balance measures mass as opposed to weight‚ so the mass you weigh will be the same on the moon as it is on earth. Gravity is taken out of the equation‚ unlike a spring balance that measures weight and would measure an article to be 1/6 of the weight on the moon as it would be on earth using the same spring balance that relied on gravity. The principle is that of moment‚ or turning force/torque)‚ calculated by force x distance. Fundamentally‚

hypothesis is one that offers the simplest most reasonable explanation and can be tested. D.the goal of an experiment is to prove that scientists are always correct in their predictions Answer Key: C Question 3 of 12 2.0 Points Microbiology continues to be an important research field for all of the following reasons‚ except: Correct A.all infectious diseases have had vaccines developed and therefore can be prevented B.many forms of genetic engineering depends on microorganisms

Unknown Microorganism: #5 Report Callie Schalk Microbiology Professor Quave November 24‚ 2015 The unknown microorganism #5 is Pseudomonas aeruginosa. It can survive in a variety of environments and at temperatures found in clinical settings (Murray et al‚ 1999). Clinical setting is referring to temperatures such as those in the hospital environment. P. aeruginosa can also survive in aqueous environments. Pseudomonas aeruginosa is found at several different sources. Nosocomial

Introduction The science of microbiology is all about microorganisms‚ what they do and how they work. Microorganisms are ubiquitous‚ and are a very important part of life everywhere since they have been around for billions of years. The two main themes associated with microbiology are (1) having an understanding of the nature and function of the microbial world‚ and (2) being able to apply that understanding of the microbial world so that the benefits to the Earth and humans are known(6). This lab

bacteria actually cause disease. He scientifically demonstrated that a disease is caused by a particular organism. He created four general guidelines to aid in identification of disease causing pathogens. These guidelines developed from his work with purified cultures of anthrax that had been isolated from dead animals. Koch also proved that the same disease could be passed from one organism to another. Pasteur proved that microorganisms could be present in non-living matter. Bassi passed both Pasteur

Identification of Unknown Report Abstract: The purpose of this lab was to determine the identity of an unknown bacteria slant culture. The unknown was identified using differential tests to determine its metabolic and morphology characteristics. Results from the differential tests indicated that unknown culture 5 is Staphylococcus aureus. Introduction: The purpose of this lab was to determine the identity of an unknown bacteria slant culture using a series of differential tests. The tests

Introduction: Each student was given unknown bacteria and was instructed to perform a variety of experimental tests that would help to identify their bacteria. During the process of identification‚ the unknown bacteria was added to many different testing medias using aseptic technique. They are as follows: lactose fermentation on eosin methylene blue (EMB)‚ TSI (Triple Sugar Iron agar)‚ Phenol
