This lab was performed to explore and discover GMOs in food that were given to test. Our group used oats, a GMO positive food, and a test food. Our goal was to find out whether the test food was GMO positive or negative and to record data accordingly. I hypothesized that the test food will be GMO positive. To see if my hypothesis had been correct we performed the process of PCR (Polymerase Chain Reaction), to find the presence of GMO positive or negative DNA in the foods. We first extracted the DNA from the foods, and then added primers to the DNA as well. I then inserted the DNA onto a gel using a micropipette. Using gel electrophoresis and a UV transilluminator we were able to view the staggering results. Genetically Modified Organisms …show more content…
But GMOs also have many adverse effects on health and the ecology of plants applied on. Genetically modified organisms disturb the ecological balance of their habitat through cross pollination. Cross-pollination is where two plants of different genetic backbone reproduce. Cross-pollination can occur over long distances as well. This allows new genes to be transferred to organic crops miles away. This makes it difficult to distinguish which crop field is organic, and which is not, posing a problem to the proper labeling of non-GMO food products. GMOs also carry unpredictable health effects for humans consuming these organisms. Our materials for the extraction of DNA included: the screwcap tubes, capless tubes, pipet tips, disposable transfer pipets, a foam microtube holder, a DI water bottle, a sharpie to label, a hot water bath, Non-GMO food, Test food, and a centrifuge. Our materials for the setup of the PCR reactions included: PCR tubes, screwcap tubes, pipet tips, an aerosol barrier, a foam microtube holder, a PCR tube holder, a 2-20 microliter micropipette, an ice bath, a sharpie to label, a plastic bag, a styrofoam cup with ice water, and a black tray with ice water. Finally, the materials for the electrophoresis of the PCR products included: Agarose gel, PCR sample tubes from previous labs, PCR tube holders, running buffers (300-350 ml), loading dye, a PCR molecular weight
“Agriculture is the most healthful, most useful, and most noble employment of man,” George Washington. Agriculture has been around for 12,000, this changed the lifestyle of people from hunting and gathering to permanent settlements with a steady food source (“Development of Agriculture”). From this, civilizations and cities grew, food could now be grown to meet the demands of the ever growing global populations. Since the development of agriculture advancement has been made to feed the population. One of the many modern advancements has been genetically modified organisms. Genetically Modified Organism, is the results of a laboratory process, where genes from the DNA of one of the species are extracted, and artificially forced into the genes of an unrelated plant or animal. Some of the unanswered questions about GMO’s have been what they are, companies that are involved,
For this experiment we used blueberries as our possible GMO food and were given a non-GMO of certified grain as our Non-GMO test sample. Before handling any samples we first needed to label two screw cap tubes with our names, date, and non-GMO and test. After labeling 500μl of InstaGene matrix was added to each tube. A mortar and pestle, that was cleaned with a mixture of bleach and water was used to maintain a sterile environment for the non-GMO food. Weighed out 1.95 g of non-GMO certified grain and placed them in the mortar. Using a transfer pipet added 5ml of distilled water for every gram of food. (See calculations part 1) Grinded the non-GMO certified grain with a pestle for 2 minutes until a slurry formed in the mortar. Added another 5ml of distilled water for every gram of food, mixed until it was smooth enough to pipet. Removed 50μl of the slurry and placed it into the screw cap tube that already contained the
In a recent article found on Facebook, David Gutierrez described how Thierry Vrain, a former Genetically Modified Organism scientist recently changed his mind on how he personally feels about genetically modified organisms. Previous to this article Vrain was for GMOs and was taking on many experiments on GMOs. However now, he says that he rejects a previous statement of his that said “biotechnology companies engineered crops, have no impact on the environment and of course that they are safe to eat” (Gutierrez, 2016). More interesting about this newspaper article, is that Vrain also now claims that GMOs cause damage to bodily organs in the human, such as the kidneys, liver and spleen. (Gutierrez, 2016). I chose this article because I wanted to see what the real science behind GMOs is, since most crops are being engineered by GMOs. I also wanted to examine why after so long Vrain changed his mind on what he thinks of Genetically Modified Organisms.
A concern that is growing is what we are eating and how it is affecting us. A lot of food is processed today, causing concerns about GMOs. GMOs stands for genetically modified organisms; this means a living organism’s genetic material has been artificially changed in a laboratory. GMOs are combinations of plant, animal, bacteria, and viral genes that do not occur naturally or even through “traditional crossbreeding” methods. Many people have questions and concerns about GMOs, and more and more people are starting not to like them. GMOs have taken over most of the US and Canada, many consumers are concerned with their safety of what they are putting in their bodies, and many are under the influence that GMOs are harmful because so many other countries have banned them or require labeling. Genetically Modified Organisms are often confused with hybridization and cross breeding. The differences are GMOs are forced together and include things that are not in nature, while the other two involve two related species being put together. GMOs are more controlled, direct, and specific. Genes are identified, isolated, copied, and introduced into other organisms. The biggest difference between breeding and GMOs would be genetic modification allows genes to transfer between species. GMOs are manipulating DNA, which many believe are harming our bodies; however, humans have been exploiting the creation of new biological variations for centuries, creating many combinations that would never
Most of the foods Americans consume today are unhealthy and harmful to the human body. Many foods available are not natural or “real” because they are genetically modified. 80% of the food we consume are processed and genetically modified.
“Between 1996 and 2008, US farmers sprayed an extra 383 million pounds of herbicide on GMOs” (Smith). For more than 20 years GMOs have been produced and placed on store shelves; there are many recognized and uncertain hazards that may affect the health of humans and the environment (Ehrenberg). Genetically modified organisms (GMOs), although they provide many benefits to the economy and food supply, are associated with numerous environmental implications; there is a noticeable increase of food allergies, mental and physical illnesses, and disorders in recent years since the introduction of GMOs. Multiple solutions have been proposed by the public, health professionals and agencies, as well as nonprofit groups, suggesting the labeling of these genetically modified organisms, or increasing the government oversight on GMOs.
Genetically modified organisms, GMO’s, and their safety are becoming one of the most important topics in the agriculture industry. The fact that scientists are changing the genome of an organism makes people hesitant to accept them as being safe. GMO corn is modified by changing a gene that causes the plant to make Bt toxin. When insects eat the corn, they also eat the toxin which is deadly to the insects. According to Cookson Beecher, a writer for Food Safety News, the Bt toxin forms a crystalline structure that the insect’s gut cannot deal with after digesting it, but it has no effect on humans when we eat it. The insects then die after ingesting the toxin, and the farmer does not have to spray pesticides on the plants. Health agencies
Genetically modified organisms as know (GMOs) is polemically in the past years. The purpose of this is to modify organisms; genetic traits in plants are to make them better for the taste, environmental and production. The plant can be stronger and defending about insects, health, herbicides and ecological threats. In some countries, this modification helps to prevent hunger in the population. The traits can be modified adding and subtracting unwanted characteristics that make the plant weak. There is a diversity of products contain GMOs.
Genetically Modified Organisms (GMOs) are often misconstrued. Most people believe that GMOs are a new way of how foods are being produced, and even though GMOs have been increasing there should still be certain precautions must be taken when consuming GMOs. Being because GMOs can be very serious issues, and since there are a lot of misconceptions about it, it is imperative that people understand what GMOs are and the problems that they are causing.
To begin, the opposition raises the possibility of genetic pollution. Jefferson states that, “The Pollen produced by these [genetically engineered] plants, carrying new genes, cannot be contained. As a result, genetic pollution of natural crop varieties and of wild plant relatives may occur.” For example, genetic pollution could result in “herbicide-resistant” weeds that are more “robust and abundant” than ordinary weeds (Miller; Mandel). In one case, an unmodified version of a canola plant was found to possess resistance to three different herbicides (Mandel). With this in mind, Mandel states that, “…genetically engineered plants may be more likely to cross-pollinate than their conventionally bred counterparts.” To emphasize, for one genetically modified squash, this statement was found to be a reality (Mandel). Eventually, Mandel warns, gene flow could lead to the extinction of unmodified wild species. Likewise, if genetically engineered plants were to spread into natural habitats, the outcome could be the complete upheaval of the affected ecosystem (Mandel). Furthermore, crops that are engineered to be pest-resistant may also pose a significant threat to both beneficial insects and pests; for example, various studies have concluded that the pollen of genetically modified corn is deadly to monarch butterfly larvae (Miller). Overall, there are several aspects of GMOs that may be detrimental to our environment.
Genetically modified organisms, GMOs for short, is a plant or animal that is created through gene slicing techniques of biotechnology which mean merging different DNA from different species to make the plant and animal stronger and faster at growing them. It introduces to the public that GMOs crop are answer to keep up the food production rate to feed the growing global population by the Monsanto Companies which is one of the company that introduce the GMOs crops. GMOs Company suggests that GMOs crops are the herbicide and pesticide resistant crops which is why it will reduce the costs and increase the production rate. However, the bugs and animals are becoming resistant to this chemical so that farmers have to use more or stronger pesticide and herbicide chemicals. It became major concern amount the public about their health that GMOs Companies introduce the use of too many pesticide and herbicide into the foods; the people also don’t like the fact that GMOs Companies are using unnatural mean to alter the plants and animals DNA, and using law and any mean necessarily to gain profit off the famers.
According to Brock Biology of Microorganisms, a genetically modified organism (GMO) is an organism whose genome have been altered using genetic engineering (Madigan, Martinko, Bender, Buckley, and Stahl, 2014). GM products include crops and animals, such as soy, cottonseed, alfalfa, papaya, canola, and sugar beets. Throughout the years there has been arguments about the safety of consuming GM products. Some countries believe that GMOs are not safe to consume while other countries believe that they are safe to consume. More than 60 countries around the world, including Australia, Japan, and all of the countries in the European Union, have restriction or bans the production and sale of GM products. However, in the U.S. GM products have been
A starving family in Zambia is in dire need of help. They travel to their countries’ capital in search of relief. The capital has plenty of food donations coming in from countries all over the world trying to help the African country in its’ time of need. The most recent food donation came from a fundraiser in America to help feed the hunger-ridden country but, there is something different about this food. The cornmeal inside of the shipment is made from Bt corn; a genetically modified organism (GMO) created for increased pest resistance. The starving Africans do not care if the food is genetically modified or not, they are only trying to feed their malnourished families. However, with heavy European influence on their government, the Zambian president at the time, Levy Mwanawasa, deemed the GM food donation “‘poison’” (Better Dead than GM-fed) and refused to distribute any of the GM donations. Instead of finding the help the so desperately needed, the starving family gets to watch the pile of food rot away in front of them.
The genetic engineering of plants is looming as one of the greatest and most intractable challenges of the 21st Century. Genetically modified organisms (GMOs) have been with us for some forty years, yet they are difficult to understand. Despite the fact that much has been written about them, controversy still surrounds their production and consumption.
Do you know exactly what you are eating, more specifically what your food is made out of? If you are eating anything that was processed more likely than not you’re eating genetically modified organisms (GMO) in some way. This is because “in the U.S. GMO are in as much as 80% of conventional processed food (Non-GMO project).” A GMO is a “genetically modified organisms” which can be a plant or animal. What makes them a GMO is that they have been genetically engineered with DNA of another organisms that has a desired trait of some kind. The DNA used can come from other animals and plants or even from bacteria’s and viruses. The reason scientist have to engineer these combination of genes is because these organisms can’t do it on there own in
