In recent years, the issue of cloning has been up for debate worldwide. Cloning is the production of one or more individual plants or animals that are genetically identical to another plant or animal. There are two different types of cloning procedures, embryo cloning and adult DNA cloning. Embryo cloning occurs when sperm and egg cells are mixed in a glass dish. After conception, the zygote (fertilized egg) is allowed to divide and nutrients are added to promote cell division. The cells then fuse with an ovum which has the nucleus removed. Adult DNA cloning is taking cells from mammary tissue from an adult. Cloning can have many good results to help humans, but others argue that it is wrong because it is immoral.
Successful cloning has occurred with livestock. Livestock like cows and sheep are not model organisms, but the farming industry has made and continues to make a big effort toward finding a way to implement the technique of nuclear transfer for livestock. Research in cloning is also occurring in primates. The reason for studying primates is the similarities with humans. This all leads us to the use of the techniques with human cells and eggs.
Cloning of humans almost is occurring. Scientists are researching by splitting embryos to execute experiments to find data relating to cell differentiation, the use of stem cells, and genetic screening. Fertility clinics use this service to help couples when a mother or father has a genetic disorder. A fertility clinic will clone an embryo, then test it for genetic disorders. If the embryo is tested negative for genetic disorders, then the fertility clinic implants a clone of that embryo. This should guarantee that the child would not have any genetic disorders.
I view cloning with mixed feelings, but I agree strongly with cloning being right. I do not believe that cloning humans to make more humans is right, but I do think cloning human organs to replace a defective gene is right. In England, scientists are heavily...
