DNA is transferred into the target plant; and, although DNA is not harmful to human health in itself because humans consume it with every plant they eat, yet the risky aspect is that scientists only transfer the genes of interest in the food. Also, the genetically modified plants hold more mutations than other plants, which may mean that the level of nutrients has been reduced or the level of allergens and toxins has been increased. However, this depends upon the procedure and intentions. Genetic modification can be used to increase nutritional content of crops, and also increase food production on the whole. If tightly regulated by government and food agencies, the genetically modified crops are safe to eat. The second article regarding genetic modification is, ‘Genetically modified humans: here and more coming soon’, written by Nick Lane (2008). Here, it is about humans and not plants. The thesis statement of this article is that a baby can be created by two mothers genetically which can save him from inheriting dreadful diseases, and this procedure can lead to the development of designer babies. In his article, Lane has illustrated the genetic modification of human beings and has described the procedure that can be used to create babies using the eggs of two women. He tells about the research work that is being carried out by a research team in UK whose purpose is the creation of an embryo with the participation of three parents and without any chance of the baby inheriting dreadful diseases. Lane further tells the role of mitochondria in the procedure. He tells that if the egg from one woman contains defective mitochondria, then these can be replaced by those attained from the donor egg from another woman, and since a mitochondrion itself contains DNA, this would mean that the baby is going to have genes from two different women or mothers. This variation in genes, on one hand, eliminates the chance of delivering mitochondrial diseases to the baby, and on the other, can affect the baby’s whole personality. However, Lane states that this procedure gives the baby chance to live with the healthiest genes. Moreover, the article tells about the fact that male mitochondria has nothing to do with the procedure as these are only present in the sperm tail and do not get the chance of penetrating the egg. Lane further talks about the ooplasmic transfer technique that was used in 1990s to control infertility but was afterwards banned by the FDA due to its vague consequences. He tells that the researchers from UK’s Newcastle University are trying another technique that involves the transfer of cell nucleus only and not the mitochondria. The nucleus of the egg with defective mitochondria is transferred to the donor egg. Male infertility can also be cured by injecting healthy mitochondria into the sperm tail which helps in sperm motility. However, scientists are not sure whether the complete elimination of serious diseases is possible by this technique or not. Comparing and contrasting the two articles shows that although both of these talk about genetic modification, but Key, Ma and Drake (2008) have talked about its impact upon plants ...Download file to see next pagesRead More

Genetic modification of foods

...? 9 Nov. Genetic Modification of Foods Genetic engineering is the process of altering the genes of a species by transferring certain traits from the genes of other species into it. Genes are composed of DNA and constitute instructions which direct the cell production of proteins which in turn, facilitate the functions of the cell. In the past few decades, there has been an immense increase in the production of genetically modified foods. Genes of plants like papaya and different types of crops have been altered with a view to making them increasingly disease resistant and enhancing their nutritional significance. Nevertheless, this is an act of meddling with the nature....

Is Genetic Modification of Foods Good

...?Genetic Modification of Food Genetic modification is an exceptional set of technologies altering the formation of organisms such as bacteria, plantsand animals. Altering is by combining different genes from organisms by combating their DNA and these results to an organism being genetically modified. According to Arup Shah, organisms that are genetically modified are those whose genetic materials have been changed in an un-natural way and the natural conditions are cross breeds or recombined (Shah 7). Benefits of Genetically Modified Foods Genetic modified foods are good and healthy for consumption and use, though they have side effects in the body mechanism and the environment. They are a wave for the future since they provide... an...

Genetic Modification

...? Genetic Modification Thesis ment Genetic food is doing more harm than good. Introduction Genetically modified foods are alsoreferred to as genetically engineered foods. These foods are as a result of special set of genetic engineering technology that lead to alteration of the genetic makeup of organisms like animals, plants or bacteria. This technology is growing at a very high rate hence becoming very common in many countries. The technology involves two genes from two different species being combined together, where genes from a different species are inserted into the DNA of that particular food or plant. However,...

Alcohol, cardiovascular disease and genetic modification

...?Alcohol's effect on cardiovascular disease and the genetic modifier of the alcohol metabolism  Introduction Alcohol is one of the more interesting factors affecting CVD, as low concentrations are said to induce protective mechanisms, while higher concentrations increase the risk for these ailments. In a review of nine, nationally representative, large-scale studies in the US, it was found that compared with those that do not drink alcohol, relative risks were 0.95 (95% confidence interval [CI]: 0.88 to 1.02) among lifetime infrequent drinkers, 1.02 (95% CI: 0.94 to 1.11) among former drinkers, 0.69 (95% CI: 0.59 to 0.82) among light drinkers, 0.62 (95% CI: 0.50 to 0.77) among moderate drinkers, and 0.95 (95% CI: 0.82 to...

Behavior Modification

...Behavior Modification The behavior that I would like to change is the affection behavior that I have developed over time for my friend Daisy. Presently, it has become difficult for me to separate the scent of the nice perfume from her as a person. In my mind, both the scent and her personality have ended up become a single identity; a symbol of attraction. It all started with associating her with the perfume that she always wears, which has an attractive scent. This association with the perform was merely an unconditioned stimulus, which I grew fond of with time, always enjoying her presence and feeling differently whenever she was around me. At first, it was a case of unconditioned stimulus (perfume), which produced an...

Genetic Modification of Human Beings is unaaceptable it strips the human race of individuality and human rights

...?Janelle Perry Eng 112 Robert Westbrook December 9, Genetic Modification Introduction Genetic engineering has been in existence for a period. This process is described as the field in which the characteristics of an organism are deliberately modified. The process occurs by the manipulation of genetic material and alteration of specific genes, and this leads to the creation of new variations of life (Uzogara 180). Most of these transformation and modifications are done in the genetic material known as DNA. This takes place through manipulation of DNA in different ways to adjust to the intended purpose. This has made it possible to put...

Genetic Modification a Hybrid DNA

...Genetic Modification a Hybrid DNA 1. The basic code of life of any organism is contained in its DNA. This molecule determines genotype as well as phenotype (external appearance and characteristics) of the organism. If DNA of an organism is altered by any means it is termed as “genetically modified organism”. The extent of modification depends on the extent of alteration of the DNA. In many cases the organism acquires altogether new features. In this manner genetically hybrid organisms can be produced – harmful, useful, good, bad anything. This is done by combining DNA from different sources. In case of genetic...
