    Genetic engineering is a type of engineering where genes are modified to find cures‚ diseases‚ and more. Genetic engineering uses the central dogma‚ which is the idea of taking. DNA transcribing it into RNA translates it into protein and expressing it as a trait. Recombinant plasmids are when DNA fragments are inserted into a plasmid vector. The recognition site is where the plasmid gets cut by the restriction enzyme which is an enzyme that cuts a DNA molecule. Recombinant DNA is the DNA being inserted

    Since GMOs (Genetically Modified Organisms) were first introduced in 1973‚ they have quickly taken over the agricultural industry; about 70% of all crops are GM products. However‚ with the rise of GMOs on the market‚ there has been a sharp increase of backlash over these products. This backlash is due to the misinformed public that made them ban or have heavy restrictions on GM products in most countries. However‚ if the public was to become informed about the effects of GMOs‚ the will be able understand

    title page picture What is the purpose for Genetically Modified Organisms? The purpose of GMOs is to make life easier for humans. GMOs are created with the well-being of humankind in focus. The many benefits that GMOs have today demonstrate this. They are used in research in medical fields‚ as well as in agriculture and pharmaceuticals. GMOs are beneficial to countries that suffer from any kind of nutritional deficiency. It is well-known that vitamins‚ proteins and fat are an important part

    Immunosuppression: Immunosuppression was performed by giving the animals synthetic corticosteroids (dexamethasone) orally at a dose of 0.25 mg/g/day for 14 successive days prior to inoculation with Cryptosporidium oocysts (Rehg et al.‚ 1988). The mice continued to receive dexamethasone at the same dose throughout the experiment. The oocysts: Oocysts of Cryptosporidium were obtained from naturally infected calves from slaughter houses by collection of scrapings of the ileal mucous membrane and cecal

    Bacterial Transformation Lab Introduction: In this experiment we transformed a strain of E. Coli bacteria without antibiotic resistance with plasmid DNA. This plasmid produces a fluorescent green glow under black light due to the gfp(green fluorescent protein) as well as antibiotic resistance. E. Coli cells will be plated on an agar medium‚ some with and some without the antibiotic ampicillin. Only bacterial cells that contain the plasmid will survive the ampicillin and produce the green glow

    Experiment 2 The induction of mutations in Escherichia coli by ethyl methane sulfonate and in Salmonella typhimurium by Tn10 The purpose of this experiment was to identify and isolate ethyl methane sulfonate (EMS) mutagenized colonies of Escherichia coli (lac-) which could no longer use lactose as a carbon source and to isolate Tn10 mutagenized colonies of Salmonella typhimurium which were induced auxotrophs and identify independent mutations. Results Mutants observed in Escherichia coli: Control

    Restriction Enzymes and Electrophoresis Bhumik Patel Phillips 1/16/11 Restriction enzymes are tools in DNA research that can cut DNA into exactly needed pieces. Certain cuts can be rough‚ while others can be clean. Certain cuts can have an organized pattern to have a staggered cut. Other cuts will leave complementary bases with them. Electrophoresis allows the manipulation of DNA to separate and organize those parts. Electrophoresis is the substrate electric movement of the separation
