1.Advantages of using retroviruses as gene transfer vehicles. Antibiotics were discovered in 1928 by Alexander Fleming when he noticed that bacteria in a petri dish were killed when penicillium molds were left in contact with them. Gene delivery can be used in cells that have been removed from the body (ex vivo gene therapy) or in cells that are still in the body (in vivo gene therapy). Gene therapy is still incomplete, requiring a lot of trials and risks in order to find the correct solution. According to the National Genome Research Institute, around 30,000 people in the United States have this condition. Genes can be delivered into cells in different ways. Gene therapy does not rely on natural discoveries for advancement. Many of today’s medications are based on discoveries from nature. Cystic fibrosis is a common and painful genetic disease that can lead to infections in the lungs, pancreas and digestive system. Gene therapy Advantages. Over 7000 distinct diseases exist today and out of which almost 80% are those which are caused by malfunctioning genes. With the help of gene therapy, these diseases are now curable and provide … On the pro side, hemophilia is an ideal genetic disorder to treat in this fashion, as it occurs due to a single genetic defect. Gene therapy can also be the answer to the cure of cancer. With more research and experimentation gene therapy may be very useful in curing and maybe even eliminating genetic disorders and cancers. Here are some of the pros or advantages of gene augmentation therapy: 1. Introducing genes into existing cells to cure genetic diseases is gene therapy. The main advantage of gene therapy is the hope of life it can give an otherwise dying human being. Retroviruses have a number of features that make them unique as gene delivery vehicles.Their life cycle includes an integrated state in the DNA of the host chromosome. The gift of a new life. Gene therapy is like a neatly packaged gift. Gene therapy has been used to treat a wide range of diseases, including cystic fibrosis. Using gene therapy for hemophilia treatment is in many ways a promising option, but it also has some drawbacks. However at the present time the disadvantages out weigh the advantages, currently germ line therapy in humans is illegal and somatic therapy … Human beings have always been prone to various health conditions, where a discovery of one treatment would apparently come with the emergence of a new disease. A second chance. Genetic Disorders Are Treatable. Rare genetic disorders today affect about 10% of the population in general. Ability to replace defective cells.
