Xenotransplantation is the transplantation of living cells, tissues or organs from one species to another such as from pigs to humans ( Medical grafting). Such cells, tissues or organs are called xenografts or xenotransplants. The term allotransplantation refers to a same-species transplant. Human xenotransplantation offers a potential treatment for end-stage organ failure, a significant health problem in parts of the industrialized world and worldwide shortage of organs for clinical implantation. It also raises many novel medical, legal and ethical issues. A continuing concern is that pigs have different lifespans than humans and their tissues age at a different rate. Disease transmission (xenozoonosis) and permanent alteration to the genetic code of animals are a cause for concern. Genetic engineering, recombinant DNA technology, genetic modification/ manipulation (GM) and gene splicing are terms that are applied to the manipulation of genes. It involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually express a protein to reach desired effects. Cloning is the process of creating an identical copy of something. Genetic recombination is the process by which a strand of DNA is broken and then joined to the end of a different DNA molecule. A genetically modified organism (GMO) is an organism whose genetic material has been altered using the genetic engineering techniques generally known as recombinant DNA technology.
Why Oryx and Crake Was Written
“Every novel begins with a what if and then sets forth its axiom. The what if of Oryx and Crake is simply What if we continue down the road we’re already on? How slippery is the slope? What is our saving graces? Who’s got the will to stop us?”
--Margaret Atwood
