Genetically modified organism - DNA Essay Example for Free

Genetically modified organism DNA Essay 1. Introduction Genetically modified foods are foods derived from genetically modified organisms (GMOS). GMOS have had particular turns led to their DNA by genetic engineering techniques. In fact,GM foods are already becoming a part of our life. (Maessen, 1997) The 2010 estimate, the most recent, says that 925 million people were undernourished in 2010 (FAO 2010). There are clearly some very real issues that need to be resolved. The purpose of this paper is to discuss whether GM foods can solve the problem of world hungry . It covers two advantages of GM food which are increasing production and effects of environment protection,finally it will cover a disadvantage for human health. 2 . Advantages 2. 1 Increase in food production GM food should be consider as a solution to slove world hunger as it produces much higher yield than conventional crops. Firstly,Crops are genetically modified in order to make them pest-resistant, drought-resistant, higher yield per acre, faster maturing, or some other improvement over natural crops. They are likely to be safer than ordinary crops since they dont have chemical pesticide on them , they are more likely to be picked and sent to market at their peak of ripeness, and are likely to last longer once you have them home in refrigerators. Its helping to resolve the worlds hungry problem. 2. 2 Advantages for environment protection One effect of GM foods is to protect environment. Genes could also be manipulated in trees, for example to absorb more CO2 and reduce the threat of global warming. Genetic Engineering could increase genetic diversity, and produce more variant alleles which could also be crossed over and implanted into other species. (Friends of Earth,2003) 3. Disadvantages of GM foods potential negative human health There are also critics objected to potential negative human health. As it has a Genetic engineering may actually counteract the processes of nature by reducing the resistance of the species to environmental extremes and diseases by creating ideal traits. Furthermore, new viruses would be encouraged to mutate into more dangerous, virulent forms that would be unstoppable. Even more horrifying is the possibility that genetically engineered products have the capability of being toxic and threatening to human and animal health. (Royal Society. 2002)Some scientists believe that introducing genetically modified genes may have an irreversible effect with consequences yet unknown. (Food Standards Agency. 2002. ) 4. Conclusion In conclusion,this paper discussed the effects of GM foods. Therefore, according to these passage that the genetically modified technology can bring more advantage and less disadvantage to us. It becomes a tendency to eat genetically modified foods. So we just be at ease to eat unless the productions are counterfeit and inferior and it is not qualified by the standard department and the GM foods almost can solve food crisis. Words (428).

My Childhood House :: Free Essays

My Childhood House When I was a child I used to live in a house which was very old and very big. To add a bit of ambience, there is one of the largest graveyards in the nation right across my street. It used to give me creeps especially around Halloween. The house was quite old if I remember rightly; I think it was built in the 1800s. There would be usual sounds of an old house, the creeks and groans and the occasional sounds here and there. The cellar was very eerie as most cellars would be. There was one room in the cellar; it was a storage room that was most disturbing. No one ever went in there unless it was necessary, no one stayed in there longer than they had to. My brother and I would swear we saw eyes watching us from the dark room sometime. My brother used to tell me the weird dreams he used to have. It seemed as if the house was trying to communicate with him. One of the dreams he had was of small children writing on the living room walls, and an adult, maybe one of the children's parent, yelling at them. Not long after, my parents decide to decorate the living room. We had friend and relative's helping us helping us strip off the wallpaper. There must have been at least twenty layers of wallpaper. Sure enough one of the layers of wallpaper had writing on it, in what looked like crayon marks. Calculations such as 1+1=2 were written on the wall. The moment I saw this I was astonished, my brother and I quickly ran to my parents and told them of this sinister discovery. My parents didn't think much of it but only coincidence; after all, my mother is an adamant disbeliever in the supernatural. My brother and I decided to investigate further, because we were kids exploration was fascinating for us. We decided to stay awake all night in our separate bedrooms that were situated on the upper level.

Clerval and Elizabeth Essay

It confirms our belief that he has become evil, but we also know the reasoning behind this,For no matter what he does he will always be shunned by mankind because of his appearance, and therefore why should he show them kindness if it is not reciprocated. The murder of William, 3 are all ruthless acts, they are also acts of vengeance towards Frankenstein. Some would however, argue that if Frankenstein had indeed made him a female partner then the torment would have ceased and Elizabeth’s life would have been spared. Frankenstein declares him a â€Å"monster† for these actions, but after all Frankenstein destroyed the creatures hopes for a female companion. However, the murders of William and Clerval can also, in some ways, be justified as acts of retribution although they can be seen as vengeful and foul. This shows the creature’s monstrous side. He is also capable of evil wickedness in the way that he coldly and calculatingly frames Justine of a murder she did not commit Mary Shelly had many themes running throughout her story bases on what she felt and what was going on around her at the time. One of the main themes is radical reform. Mary Shelly once described the French Revolution by saying â€Å"†¦ the giant now awoke. The mind†¦ received the spark which lit it into an inextinguishable flame†¦ â€Å". This could equally be her describing the creature. During â€Å"The French Revolution† never before were seen acts that were carried out by the common people, the poor were now daring to overthrow the rich. Mary Shelly witnessed the destruction of her Mother and Father’s reputation caused by their revolutionary fervour and managed to distance herself from it. Perhaps Mary Shelly’s Frankenstein is an allegory of the French revolution. The creature could be seen as a demonstration of the consequences of unleashing an uncontrollable force, Frankenstein could be seen as the initiators of the French Revolution who fail to control their followers. Frankenstein is very irresponsible of his creation and shuns it from the moment it comes to life, he also fails to keep the creature under control. The creature is then rejected, cursed and unloved by everyone, no matter what he does, he deals with his hurt and his anger by destroying everything he comes across and eventually he destroys his creator, Victor. Victor’s lack of responsibility towards the monster has resulted in his own downfall. This is what happens to the people who lead the way in French Revolution. They too created a monster who grew out of control and eventually the leaders were executed. Frankenstein’s creature begs to be treated with kindness and respect, but he is spurned and rejected. His moral monstrosity of the terror is also a creation of the French Aristocracy. If the Aristrocracy had acknowledged and paid gratitude and respect to the common people, they would of reciprocated in kind and the need for a revolution would be unnecessary. . Both the creature and his creator are warnings/demonstrations to the world: the powerful must esteem and respect the powerless, or revolution will ensue. Now I come to answer the question â€Å"does Shelly intend us to respond to the creature as a monster†. What Mary Shelly is saying is that monsters aren’t born they are made. This is evident in the way that the creature is treated. When he is first introduced to the world he is a kind, loving being, perhaps even an example of goodness. But when in the face of people he is rejected, cursed upon and unloved, this in effect turns the creature into a monster. Mary is also saying that reform, when it is controlled and in the right hands is not a bas thing, but when we fail to control it will grow uncontrollable and become evil.

A Brief Note On Parkinson s Disease And Its Effects On...

Meghan Covrig Adkins Honor English III-4th 1 November 2016 Behind the Mask Imagine waking up one morning, as stiff muscles make movement nearly impossible.As you try to brush your teeth, your hand keeps shaking. Getting into the shower, you brace yourself against the wall to keep from falling. Then you struggle putting on your clothes. Sitting at the table eating your breakfast, you begin to cough, sputter, and choke on what was an appetizing meal. The life of a person with Parkinson’s Disease is much more difficult than the life of a person without the disease. Everyday tasks seem grueling and unattainable. Scenarios, such as the one above, occur every day and wreak havoc on innocent people’s lives. Even though the number of patients with PD continues to rise, the government still does not provide the adequate funding to answer questions surrounding Parkinson’s Disease. Parkinson’s Disease (PD) is a chronic and progressive disorder that affects the Central Nervous System (CNS). The Central Nervous System is the portion of the body that encompasses the brain and spinal cord (Abromovitz 13). Parkinson’s Disease is characterized by an abnormal motor output. The output is irregular because impulses are blocked and can not be interpreted. Since the impulses can not be deciphered, the messages are misconstrued and the brain confuses commands (Hains 1). According to a 2006 survey, five percent or 1.5 million Americans have Parkinson’s Disease.
