Genetic Engineering: Far Outweigh The Risks

Decent Essays

Despite the occasional risks and challenges that may arise in the process, genetic engineering provides more benefits that far outweigh the harms. Genetic engineering is a subject unfamiliar to the general public because not only has it not had much exposure to people outside of the scientific world, but it is also extremely complex and still has several applications yet to be found. “Recombinant DNA results when scientists combine nucleotide sequences (pieces of DNA) from two different sources-often from different species-to form a single DNA molecule” (Campbell 220). Recombinant DNA is the most widely used in genetic engineering and is what replaces unwanted genes. Gene therapy is beginning to be used by scientists and researchers to cure …show more content…

There currently is no known cures for these mosquito diseases, such as malaria, but with the help of genetic engineering and gene manipulation, scientist Anthony James “used CRISPR to engineer a version of Anopheles mosquitoes that makes them incapable of spreading the Malaria parasite” (Michael 4). The genetic modification of this species of mosquito can and will be used to create a whole new population of mosquito that are incapable of spreading Malaria. Furthermore, this process of recreating a population of non-malaria carrying mosquitos is fairly quick and easy. Scientists can go capture several Malaria carrying mosquitos from a large population, remove the mosquitos’ disease genes and replace them with a gene that makes the disease sterile. After modification, scientists release all of the captured mosquitoes back into the large population in the wild and hope those mosquitos mate so that the new gene that makes the disease sterile will be passed onto offspring and in a relatively short time create a large population of disease free …show more content…

Both “Malaria and HIV-1 are 2 of the most common infections in sub-Saharan Africa and, to a lesser extent, in other developing countries. It is estimated that 38 million Africans are infected with HIV-1, whereas 300 million to 500 million suffer from malaria each year” (Whitworth 3). These two disease go hand in hand to cause the millions of deaths that occur in Sub-Saharan Africa every year. HIV, a disease that weakens immune system by attacking and killing T-cells in the body, allows for Malaria to take a greater and deadlier effect on the already weakened human body. HIV/AIDS might eventually be a thing of the past because CRISPR has been used to get rid of diseases in animals, such as cystic fibrosis, muscular dystrophy and a form of hepatitis and scientists are now using these methods to try to cure AIDS (Michael 2). Curing of HIV or AIDS is no simple task since the disease is extremely resilient, plentiful and is present in the majority of the body’s blood stream. Scientists would have to somehow alter the genes of the body's T-cells to resist being taken over by the HIV or alter the genes of the HIV to not be able to spread and infect other body cells. Genetic engineering is the only method that provides this realistic possibility of being able to treat and cure HIV and AIDS that otherwise would
