These retroviruses then help to code for the infected DNA which can then form or remove a gene accordingly. In general there are two types of gene therapies known as the germ line therapy and the somatic gene therapy. In germ line therapy a gene is directly inserted into the egg or sperm so that the gene is incorporated into the original genes. In somatic gene therapy the genes are inserted into the somatic cells which are spermatozoa and ova cells (Kelly 2007). Gene Therapy has yet not proved to be successful but it can be used in hereditary diseases such as cancer and nervous tissue disorders. Although gene therapy drugs have yet not been introduced in the market as a full, China has allowed a gene therapeutic to be allowed in their market to treat cancers. Gendicine is the name of the drug which can be used for treating cancers in China. Gene Therapy is originally targeted for diseases like leukemia, anemia, hemophilia and other cancers (Guo & Xin 2006; Peng 2005).
Human Genome Project was a project launched in the year 1990 by international authorities to find out the sequencing of the human genome along with the identification of the chemical base pairs. The project was completed in 2003 and helped to know much about the structure of the human genome. It is this human genome project which helped to know a lot about the structure of chromosomes, the proteins coded by the genes, and the number of genes in a human being. Human Genome Project has had worldwide recognition but many of the individuals living in the world have also become concerned regarding the results of the project. In some of the societies the project is not ethically accepted because of different reasons. Many individuals believe that the results of the project would help the scientists to make their way through to cloning and other experimentation involving human beings. It is this Human Genome Project which can further excel the
