premise: We like to think of ourselves as unique but we are in fact 99.9 per cent genetically identical. DNA, which comprises the chemical code, governs the construction and function of every cell in our body. The Human Genome Project mapped the sequence for human DNA and provided a blueprint of the DNA shared by every person. But what of the 0.1 per cent that is not common to all mankind and was left out of the Human Genome Project blueprint? It is responsible for all individual idiosyncrasies and the differences between racial and ethnic groups. If it were not for this minute percentage there would be no individual differences. We would be clones. Individual differences could be greatly increased if we were to think the unthinkable and allow genetic engineering of the human DNA. This would involve inserting genes from one cell into another and changing that cells DNA and its characteristics. In theory it would be possible to take the DNA from an entirely different species and insert it into human cells. Such radical modifications could certainly make us much more unique.
hypothesis: It can be inferred from the passage that the author does not approve of the genetic engineering of human DNA.
