Disadvantages Of Transgenesis
Transgenesis Essay (Plants) Introduction: Genetic engineering is the process whereby the DNA is altered in an organism’s genome. In this essay I will discuss Transgenesis by discussing the manipulation for it and biological implications surrounding the process, as well as advantages and disadvantages of transgenic plants and animals. Definition: Transgenesis is the process of introducing an exogenous gene - called a transgene - into a living organism so that the organism will show a new property and pass that specific property onto its offspring. Manipulation/Technique for Transgenesis: There are a variety of techniques involved in Transgenesis, however the technique I will be specifically explaining is the Agrobacterium as a vector …show more content…
Firstly, a disadvantage of transgenic plants is the reduction in genetic diversity. This is a disadvantage because there is less variation among the transgenic plants, which means the transgenic plants will have almost identical genes, therefore if a new disease is introduced in the transgenic plant population, and if the transgenic plants have the unfavourable allele (allele that cannot resist the certain disease), then the transgenic plants will die due to them not having the resisted allele. Consequently the genetic variation for the particular species will be decreased and the population will also suddenly decrease. Not only does transgenesis reduce genetic variation among the transgenic population, but also transgenic plants will cause less effective antibiotics to be produced. Evidence indicates that certain crops that have been genetically modified by scientists have germ-killing (antibiotics) properties inserted into them in order to make the (transgenic plants) immune to certain diseases. However, when consumed, the antibiotic properties are left in your body, and therefore can make other antibiotics less effective/inefficient. Nevertheless there also advantages of transgenic plants. For example, transgenic plants that are made into food can withstand long-distance transportation. The transgenic crops are picked, when still green and have the ability to ripen during transportation methods therefore extending a longer shelf life. Even if the transportation distance is far, the food will reach its destination without spoiling. Furthermore, transgenic plants have the ability to be resistant to pests, and this is a huge benefit for farmers. For example, “Papaya ringspot

Those chemicals can increase the risk for certain illnesses, such as diabetes and cancer. GMO's are meant to be the perfect organism, however many factors can go wrong with so much genetic modification since its going against nature (Food Policy Institute 2003). The process of how GMO's are created is through the help of gene transfer technology. The desired gene from another organism is placed in the other organisms genome
Persuasive Essay On Genetically Modified Foods
1150 Words | 5 PagesAnother example is of a genetically modified tomato called flavor saver. The tomato is larger, tastier, and stays fresher longer than commercial tomatoes on the market. Combining conventional tomato genes with the genes of an arctic trout produces the flavor savor. Nevertheless, questions such as “Will people with seafood allergies be able to consume the tomato?” and “Will the trout genes in the tomato enable new bacteria growth, and thereby make the tomato hazardous to eat?” have still not been answered.
What Are The Pros And Cons Of Genetic Modification
1694 Words | 7 PagesGenetic modification has risen to the public eye as a highly controversial issue over the past few decades. Starting with the FLAVR SAVR tomato in 1994, we can now genetically alter any organism, including ourselves. We can, and have, manipulated crops to resist insects or herbicides and animals to glow in the dark, grow faster, change their color, or even make spider silk. However, out of the limitless applications of genetic modification, three in particular stand out as relevant to our everyday lives: genetically modified foods, gene therapy, and designer babies.
Core Competencies Of Monsanto
335 Words | 2 PagesMonsanto’s core competency is the insertion of traits into crop plant genomes (Paulis). Monsanto genes are found in the vast majority of soy and corn grown in the U.S. and its products and technologies are licensed to many commercial farmers. It is leading in terms of operational leadership as Monsanto’s technologies have enabled the seed business to be more relevant to meet the demand in food industry. The company has a strong R&D structure to continually innovate products either through breeding or biotechnology. Through the breeding path, plant genes are combined and altered by conventional cross-breeding methods a swell as by technology- and computer-assisted methods.

Genetic Engineering In Medicine
805 Words | 4 PagesGenetic Engineering is a process where we manually remove our gene of interest from an organism and insert it into another organism. This results in the organism possessing the particular trait we want from the organism. Applications of genetic engineering can be found all around us. They can range from certain crops that are pest resistant to the food with higher nutritional value and even to the medicine that we consume. Genetic engineering began in 1973 when Herb Boyer and Stanley Cohen created the first recombinant deoxyribonucleic (DNA) organism.

Artificial Selection
1183 Words | 5 PagesAlthough the list of advantages for selective breeding is boundless, there are a long list of disadvantages. With mutations comes the risk of new diseases as well as other health affects. Some health affects may skip the plant and affect those around it such as humans or other organisms that consume the plant. Genetically altering a plant can lead to shorter life spans as well as the ruining of the fruits made by the plant. A less extreme but still unsatisfying loss could be a poor tasting crop or one that may decay much faster.

However there are few that are more significant and important of these three advances; the development of gene therapy and its first successful use worldwide clinically, the use of monoclonal antibodies in order to treat cancer, and the sequencing of the human genome. There is also a problem in the world at the moment with antibiotic resistance in harmful bacteria and the challenge has been set to find new antibiotics in order to combat these bacteria. In the next decade, significant steps will be made towards this advance.
Disadvantages Of Cloning
1045 Words | 5 PagesDespite our advances in medical technology, each year, thousands of people suffer and die due to organ failure. There are various causes to organ failure, either by physical damage, genetic mutation (exogenous factors: e.g. sunlight, radiation, smoking, etc..), and genetically inherited diseases. At this point in time, there are numerous of ways to solving organ failure, such as through the use of dialysis, pacemakers, drugs, etc… But in the end, the most sustainable way of potentially curing organ dysfunction is through organ transplants. Those who have passed away due to organ failure did not die because of the lack sufficient medical treatment, in fact the success rates of organ transplants operated around the world are all over 80%, so
Genetic Engineering Persuasive Essay
694 Words | 3 PagesIntroduction: ¬¬¬¬¬¬ People have been manipulating the genetic make-up of plants and animals for countless generations. This is referred to as traditional cross breeding and involves selecting plants and animals with the most desirable characteristics (e.g. disease resistance, high yield, good meat quality) for breeding the next generation. Today’s techniques use new ways of identifying particular characteristics and transferring them between living organisms. For example, it is now possible to make a copy of a particular gene from the cells of a plant, animal or microbe, and insert the copy into the cells of another organism to give a desired characteristic. Foods derived from genetically modified organisms are called “GM foods” or “Frankenfood”.
