These issues need to be considered by all stakeholders, including veterinarians, to ensure that all parties are aware of the ethical issues at stake and can make a valid contribution to the current debate regarding the creation and use of genetically engineered animals. In addition, it is important to try to reflect societal values within scientific practice and emerging technology, especially publicly funded efforts that aim to provide societal benefits, but that may be deemed ethically contentious. As a result of the extra challenges that genetically engineered animals bring, governing bodies have started to develop relevant policies, often calling for increased vigilance and monitoring of potential animal welfare impacts 2.
The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer.
But science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history will science be able to so deeply affect our lives as genetic engineering will undoubtedly do. With the birth of this new technology, scientific extremists and anti-technologists have risen in arms to block its budding future.
Spreading fear by misinterpretation of facts, they promote their hidden agendas in the halls of the United States congress. Genetic engineering is a safe and powerful tool that will yield unprecedented results, specifically in the field of medicine.
It will usher in a world where gene defects, bacterial disease, and even aging are a thing of the past. 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 dependent on the understanding of how individuals pass on characteristics to their offspring.
These early studies concluded that each organism has two sets of character determinants, or genes Stableford For instance, in regards to eye color, a child could receive one set of genes from his father that were encoded one blue, and the other brown.
The same child could also receive two brown genes from his 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 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. They were all later accredited with the Nobel Price in physiology and medicine in Lewin 1.
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 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 a particular location called a nucleotide base, which makes up a DNA molecule. 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. The possibilities of genetic engineering are endless.
Once the power to control the instructions, given to a single cell, are mastered anything can be accomplished. For example, insulin can be created and grown in large quantities by using an inexpensive gene manipulation method.One of the leading researchers compares genetic engineering to the American and French Revolu tions or the birth of liberty.
All the old ideas are being thrown overboard.
Genetic engineering has changed the pathway of biology more than any other single scientific event of the 20th century. Genetic engineering, sometimes called genetic modification, is the process of altering the DNA in an organism’s genome.
This may mean changing one base pair (A-T or C-G), deleting a whole region of DNA, or introducing an additional copy of a gene.

Experts debate whether genetic engineering of unborn children, also called designer babies, would lead to a healthier society or eugenics.
