Why do scientists mess around with DNA?
Scientists “mess around with DNA” because they can use the knowledge they gain from this to improve our lives. DNA studies affect medicine, agriculture and conservation. Genetic engineering can treat diseases and our susceptibilities to them. We will also be able to produce new organs for people with faulty ones through tissue cultivation methods (cloning) and eliminate the need for these transplant recipients to take immune-suppressing medications for the rest of their lives. Genetic engineering can enable us to revive genes for endangered species by allowing us to use copies of genes from dead specimens now found only in museums. There are thousands of relics from tigers, mongolian wild horses and white rhinos all over the world. These relics represent some of the diversity that could be restored to modern populations that are now suffering from genetic impoverishment. We will be able to repair some of the damage we have inflicted over the centuries. Genetic engineering and cloning c
