The Advantages and Disadvantages of Genetic Engineering

Genetic engineering has been a major topic of discussion ever since
'Dolly' the sleep was cloned. Its raises ethical, moral and religious
questions due to the fact it is tampering with the makeup of
organisms, and certain religions believe it is not our right to do
this.

Genetic engineering involves the re-arranging of DNA sequences,
artificial horizontal gene transfer and cloning. There has been little
progress in the re-arranging of genes in the last several years, due
to the complexity of the problem, as there is no technique developed
to analyse the sequence of DNA quickly. The analysis of E-coli DNA
sequence took 12 years! Artificial horizontal gene transfer is a
method of gene transfer between different species. Scientists transfer
some known 'small' genes to another species to improve their
functions. There are many unknown factors of this, as well as a low
success rate, so very few products exist. As for cloning, the only
clone is 'Dolly' the sheep, who was genetically duplicated from a
complete set of adult chromosomes. Scientists have been unable to
repeat the experiment, so many of them question its validity.

There are advantages to genetic engineering; despite the fact we are
more informed of its possible dangers. These advantages are mainly
known in the advantages of genetically modified crops (or GM foods).
Plants can be produced that are resistant to plant diseases (like
fungi) and animal pests (like insects). Plants could also be created
that could survive in less favourable conditions, such as poor soil
quality, such as giving plants a nitrogen fixing cap...

...ke.

Another argument is that the manipulation of plant and animal DNA
could be leading to the genetic manipulation of humans, which would
cause a public outcry.

Should we be allowed to tamper with genetic make-up when it has
progressed without interruption from humans for billions of years?
Religious people believe we should not tamper with what god created.
Should we be carrying out research into an area many people feel
strongly against? These are the kinds of moral questions we should
consider before we take this any further, although scientists are
proceeding with research without fully considering the beliefs of
other people, believing they are doing is right. Surely we should be
seriously considering the implications of our actions involving
genetic engineering, as the next breakthrough could be tomorrow.

Genetic Engineering: Pros and Cons Essay

- Our world has finally begun its long-predicted descent into the depths of chaos. We may not yet realize it, but more and more problems plague the very state of our humanity with each passing day, such as cancer, famine, genetic disorders, and social elitism. It seems as though there is little hope, although a new solution has finally emerged, in the form of genetic engineering. It is apparent, however, that currently we cannot proceed, because while there are an abundant amount of advantages to genetic engineering, it is not a utopian process; criticism includes its practicality, theological implications, and changes in modern social structure....   [tags: Eugenics, Ethics]

The Pros and Cons of Genetic Engineering Essay

- Genetic engineering is a process in which scientists transfer genes from one species to another totally unrelated species. Usually this is done in order to get one organism to produce proteins, which it would not naturally produce. The genes taken from one species, which code for a particular protein, are put into cells of another species, using a vector. This can result in the cells producing the desired protein. It is used for producing proteins which can be used by humans, such as insulin for diabetics and is also used to make organisms better at surviving, for example genetically modifying a plant so that it can survive in acidic soil....   [tags: Genetic Engineering Essays]

Essay about The Pros and Cons of Genetic Engineering

- ... One thing it can do is enable hereditary diseases to be treated so they are not past off to their offspring. Genetic engineering can also enable scientists to make animals have certain characteristics and enable to them to remove certain characteristics. Take Jackie for example she was a normal pig when the expirement first started. Scientists then took the glowing gene from a jellyfish and transplanted the gene from the pig with the one of the jellyfish. Soon after the lights were shut off and Jackie was glowing....   [tags: technology, environmental issues]

The Pros and Cons of Genetic Engineering Essay

- The formal definition of genetic engineering given in the Merriam-Webster Dictionary is “the directed alteration of genetic material by intervention in genetic processes”. Stated in another way, it is a scientific alteration of the structure of genetic material in a living organism. There are many different methods in genetic engineering, but the goal of all the methods is to manipulate the genetic material (DNA) of the cells in a living organism in order to either change it hereditary traits or to produce biological products....   [tags: essays research papers]

The Pros and Cons of Genetic Engineering Essay

- Within the field of human embryo research lies a controversial science that could redefine prenatal care: genetic engineering. Genetic engineering not only offers the possibility of eliminating birth defects and genetic illness, but also presents the moral ambiguity of eugenics. The acceptabilities of genetic engineering, assuming that it will be available in the foreseeable future, must be explored if society is to fully benefit from it. The most prominent and perhaps the most acceptable reason given for genetic engineering is its potential use in preventative medicine....   [tags: Persuasive Argumentative Essay Examples]
