Fetal DNA modification signified a new era in the medical science and in the study of genes on the whole. This term defines a type of germ line gene therapy. It is called fetal for the reason that it is only applied to fetus. It is explained due to the fact that their gene makeup abnormalities could cause serious hereditary disease. In case if a genetic disease is recognized in the process of testing the amniotic fluid, the fetal DNA therapy is considered to be the best possible choice. Taking into account that the human genome project is almost accomplished, today we already possess the knowledge about every gene, its location in the human body and its role. Having this valuable knowledge, researchers can deal with viruses, while changing their genetic makeup. This can eventually help fix the abnormalities that the growing fetus may have. Because of the evolution, viruses have evolved enough so that today they are capable of penetrating the cell membranes, occupy the cells and take over their reproductive abilities. As a result, the cell can read the genetic code of the viruses instead of its own and replace it with the viruses DNA. However, the latest studies have shown that we can inject virus DNA that got its genes sequence changed and by means of this, fix what is genetically wrong. Eventually, the child will be born with no hereditary disease. The potential issues with this kind of treatment is that we can create mentally or physically retard babies in attempting to modify their genes, as long as we do not possess enough of information about the procedure. One more issue is that many people argue that it is unacceptable from a religious point of view and that it is nothing but violating the natural order of things. In other words, the ethical side of the problem creates a lot of obstacles on the way to achieving ultimate progress in this deal.
As for the process of modification, there are two ways to achieve it. First of all, it can be done through adding some genes. Second of all, it can be done through removing genes. Both of the modification types are appropriate in different situations. While genetic modifications are broadly exercised in plants, its application to animals and humans are is still criticized hugely. Despite of a number of advantages, including saving lives and curing diseases, some people still argue that this kind of modification is going against nature and violates its balance.
