Genetic engineering proscons essay
The most prominent and perhaps the most acceptable reason given for genetic engineering is its potential use in preventative medicine The petunia turned red but also produced more leaves and shoots, had lower fertility and was more resistant to fungi.
Advantages of genetic engineering essay
Making yourself aware of all aspects of genetic engineering can help you to form your own opinion. Human genetic engineering science modifies human beings genotypes before birth. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code. Basically, scientists take DNA of one product and put it into another product to get a mixture of traits from both products. Produce New Foods Genetic engineering is not just good for people. Genetic engineering involves the re-arranging of DNA sequences, artificial horizontal gene transfer and cloning. What is more, such procedures may not be within the means of everyone. Crops that are genetically engineered may take the place of natural weeds and thus harm natural plants. Gene therapy is available only to the very rich and elite, which means that traits that tend to make people earn less money would eventually die out. One of the main advantages of genetic engineering is genetically modified crops GMOs often behave very differently when taken from the laboratory, greenhouse or field trial situation into the real-life context where they will be used, e. Is that right?
Like all sciences it is hard to predict outcomes, so far there have been more failures being told than success stories. With genetic engineering we can design foods that are better able to withstand harsh temperatures — such as the very hot or very cold, for instance — and that are packed full of all the right nutrients that humans and animals need to survive.
Concentrating on the genes, therefore, is one-sided. The genes taken from one species, which code for a particular protein, are put into cells of another species, using a vector. However, they examine the organisms produced in detail, sometimes taking them through breeding programs for years to be sure that they are behaving in the way that other normal members of the same species behave which have not had the genetic modification.
You cannot simply stop people from having children if they suffer from a disease like this, therefore genetic engineering can help to ensure that their children live long and healthy lives from either the disease itself or from carrying the disease to pass on to younger generations.
The human body is so complicated that scientists have to be able to predict what sort of affects their actions will have, and they simply cannot account for everything that could go wrong.
Genetic engineering good or bad essay
With genetic engineering we can design foods that are better able to withstand harsh temperatures — such as the very hot or very cold, for instance — and that are packed full of all the right nutrients that humans and animals need to survive. In the s, electricity was forecast to become too cheap to make it worth metering, but the reality is that society is left with a legacy of nuclear waste the cost of dealing with which will place an immeasurable burden on future generations. Here are just a few of those disadvantages: 1. GE is a very precise way of introducing desirable traits into economically useful organisms. The fact that horizontal gene transfer occurs all the time in nature, e. Inserted genes can disrupt the function of existing genes in ways, which may not show up until later generations. One thing it can do is enable hereditary diseases to be treated so they are not past off to their offspring. This is done to selectively breed desired traits or to create plants with increased resistance to pesticides and increased tolerance to herbicides. All attempts to define what species barriers are have so far had various shortcomings. Scientists have been creating genetically modified organisms and products for years. We may also be able to make our foods have a better medicinal value, thus introducing edible vaccines readily available to people all over the world Cons of Genetic Engineering Perhaps more obvious than the pros of genetic engineering, there are a number of disadvantages to allowing scientists to break down barriers that perhaps are better left untouched. For instance, Cystic Fibrosis , a progressive and dangerous disease for which there is no known cure, could be completely cured with the help of selective genetic engineering. GE often, but not always, needs to use bacteria, viruses or plasmids as vectors to shuttle the genes of interest into the target organisms. Genes and their proper expression as structural, regulatory or enzymic proteins are merely one of the necessary conditions for the idea underlying an organism to manifest.
But we now have the knowledge and technology to do this on a drastic scale the world has never seen. I have chosen to present my work by discussing the religious arguments in favour and against genetic engineering, designer babies, should parents have the right to choose their child's looks, sex and intelligence levels.
Crops that are genetically engineered may take the place of natural weeds and thus harm natural plants. Allowing parents to choose traits would enable newer, better, stronger genes to be passed on from generation Related Documents Essay Genetic Engineering : Be Controlled By Law Control Genetic Engineering Genetic engineering is the deliberate modification of the characteristics of an organism by manipulating its genetic material.
