Human genetic engineering (H.G.E) is an advancing field of science that has caused controversy world wide. Firstly, human genetic engineering is a way manipulating and modifying our genes for several different purposes, whether it is to cure a genetic disorder or to simple perfect the way we look. This modification can target the gametic cells (sperm and ova) if the desired effect is to pass down the generations to resulting offspring, this is also known as germline therapy, however as human genetic engineering is still limited this form of therapy is illegal is most countries. Alternative forms of manipulating the human genome are to simple remove the faulty gene and replace it with a functioning gene. This can be obtained through the use of vectors. For example, Cystic Fibrosis is due to a defective gene, this gene can be removed from the body using nanotechnology; meanwhile a healthy gene is inserted into a vector (often a bacteria or virus) which is then introduced to the genome. This new gene is taken up by the body and Cystic Fibrosis is cured!
In theory, this seems simple and easy enough, however in execution it is far more complicated and many complications arise. Since the mapping of the genome scientists have found a way to manipulate and work to our advantage human genetics. Theoretically in the future through the continued development of human genetic engineering researchers and scientists would have discovered a way to cure many diseases from Cystic Fibrosis to AIDS and cancer. Currently the controversy that has risen is the argument between whether H.G.E is ethically right. Although this advance may lead to cures to save lives, does it also gives the fundamental edge to man kind’s race for perfection?
