Imagine a world full of mini Hitlers seeking world domination, killing millions as their solution to establish a superior race or bunch or 2 headed humans eating a pig with 6 legs. These scenarios may sound like something out a science fiction novel, but this is the kind of things that people think about when they hear the words genetic engineering
Genetic engineering is now an important part of this world. It is used to cure diseases, develop food that grows faster and food thats healthier. Without genetic engineering it will not be possible to feed the 10 billion humans expected by the year 2030. Only by using this new technology can we increase the food production enough so that it is possible to feed this growing world. This can be done by producing plant varieties that is more precisely adapted to local conditions. This also helps poor farmers by reducing their expenses such as pesticides.
In developing worlds there are over 100 million children with vitamin A deficiency causing huge problems such as blindness. These people eat mainly rice and rice has no vitamin A. Right now the only way they can get enough vitamin A is by costly supplements that doesnt reach everyone. So scientists are genetically engineering rice so that it contains vitamin A, and this rice seed could be distributed to the poorest areas of the world, a brilliant and simple idea.
So how can consumers living in developed world benefit from plant biotechnology? Using modern biotechnology scientists have already produced food with improved flavour, food that is better for health and food with better qualities. Examples of these are apples and sweet corns that are insect resistant, frost resistant strawberries and seedless grapes.
One of the main reasons why people oppose genetic engineering is that they think biotechnology is an imprecise science and so it will likely to result in unanticipated outcomes and dangerous surprises. But did you know that people have been cross breeding plants and animals for thousands of years? And every time they do this they are randomly recombining up to 40,000 genes. If using biotech scientists are just moving 1 or 2 specific genes, and the effects can be monitored and tested more easily. So in comparison genetic engineering is a lot safer than traditional cross breeding.
Another important aspect of genetic engineering is its medical purposes. For example cystic fibrosis maybe cured if a gene can somehow enter the cells that line that lungs, it will begin producing the critical proteins that CF patients lack. Scientists are working on this right now and some patients receiving this treatment have already been able to produce this protein in small quantities.
Genetic engineering and the knowledge about the effects of DNA variation among individuals can lead to revolutionary new ways to treat and even prevent thousands of disorders that affect us. Learning about non-human organisms DNA can also help us understand their natural capabilities which can be applied towards solving challenges in health care, energy sources, agriculture, and environmental cleanup

Science is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from an analytical engine, to a calculator, to a computer. However, science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history has science be able to as deeply affect our lives as genetic engineering will undoubtedly do. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted.
The first step to understanding genetic engineering and embracing its possibilities for society is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependant on the understanding of how individuals pass on characteristics to their offspring. Genetics achieved its first foothold on the secrets of nature's evolutionary process when an Austrian monk named Gregor Mendel developed the first "laws of heredity." Using these laws, scientists studied the characteristics of organisms for most of the next one hundred years following Mendel's discovery. These early studies concluded that each organism has two sets of character determinants, or genes (Stableford 16). For instance, in regards to eye color, a child could receive one set of genes from his or her father that were encoded one blue, and the other brown. The same child could also receive two brown genes from his or her mother. The conclusion for this inheritance would be the child has a three in four chance of having brown eyes, and a one in three chance of having blue eyes (Stableford 16).
Genes are transmitted through chromosomes which reside in the nucleus of every living organism's cells. Each chromosome is made up of fine strands of deoxyribonucleic acids, or DNA. The information carried on the DNA determines the cells function within the organism.
DNA discovery is attributed to the research of three scientists, Francis Crick, Maurice Wilkins, and James Dewey Watson in 1951. They were all later accredited with the Nobel Prize in physiology and medicine in 1962 (Lewin 1).
"The new science of genetic engineering aims to take a dramatic short cut in the slow process of evolution" (Stableford 25). In essence, scientists aim to remove one gene from an organism's DNA, and place it into the DNA of another organism. This would create a new DNA strand, full of new encoded instructions; a strand that would have taken Mother Nature millions of years of natural selection to develop. Isolating and removing a desired gene from a DNA strand involves many different tools. DNA can be broken up by exposing it to ultra-high frequency sound waves, but this is an extremely inaccurate way of isolating a desirable DNA section (Stableford 26). A more accurate way of DNA splicing is the use of "restriction enzymes, which are produced by various species of bacteria" (Clarke 1). The restriction enzymes cut the DNA strand at nucleotide bases both upstream and downstream from the gene to be transfered. Now that the desired portion of the DNA is cut out, it can be joined to another strand of DNA by using enzymes called ligases. The final important step in the creation of a new DNA strand is giving it the ability to self-replicate. This can be accomplished by using special pieces of DNA, called vectors, that permit the generation of multiple copies of a total DNA strand and fusing it to the newly created DNA structure.
Another newly developed method, called polymerase chain reaction, allows for faster replication of DNA strands and does not require the use of vectors (Clarke 1). In nature, most organisms copy their DNA in the same way. The PCR mimics this process, only it does it in a test tube. When any cell divides, enzymes called polymerases make a copy of all the DNA in each chromosome. The first step in this process is to "unzip" the two DNA chains of the double helix. As the two strands separate, DNA polymerase makes a copy ... more

Fatal familial insomnia
fatal familial insomnia Fatal familial insomnia is a genetic disorder. It manifests itself by many symptoms due to the degeneration of a certain part of the brain, the thalamus. The disease also results in the formation of amyloid plaques. This is the build up of a waxy substance made of proteins associated with polysaccharides. The disease is a result of a mutation of a normal protein that is associated with brain tissue. This is the prion protein. In the case of fatal familial insomnia, the mu...

Cloning Someone once said that if you give someone an inch they would take a foot. Biotechnologist would like to receive an inch of allowance from the government to start the cloning process here in the United States. The fear, however, that cloning may become too advanced is a relevant response. Cloning is the copying of genes, or DNA, of one organism to be used in the creation of an identical one. It is similar to genetic engineering, which is the manipulation of the genes. HOW IS CLONING DONE...
Bio-Technology The short-term future of biotechnology in production agriculture looks bleak. The unattractive truth is that economics, not science can play a larger role in the future of biotechnology. Currently, some of the largest biotech companies are losing money buying up smaller companies. This reduction in competition is good and bad for the biotech companies. They can and must raise their prices to the producers to cover the costs of buying the other companies, research and development. ...
