In science, cloning is defined as the processes used to create copies of fragments of DNA, cells or organisms. Human cloning is the creation of a genetically identical copy of a human. A clone is an organism that has generally identical genetic composition to another organism. Cloning could happen artificially, which is done in a lab or naturally, which is the case in identical twins. Cloning is broken down into three different types: gene cloning, reproductive cloning and therapeutic cloning. Gene cloning makes copies of genes or pieces of DNA. Reproductive cloning makes copies of the animals as a whole. Therapeutic cloning makes embryonic stem cells for experiments to create tissues to replace tissue that has been affected by disease or an injury. However, the question human cloning raises is, is it ethical? Many people are quick to answer no to that question, but there are just about the same amount of people willing to say that it is just like any other advance in science.
The technique that was used to cloned a sheep in 1996, scientists had to make a few changes to it to make stem cells in a lab that genetically match the cells found in human embryos. Until now, researchers were harvesting the cells from leftover embryos from in vitro fertilization. They were trying to come up with ways to turn adult cells into embryonic ones, but had difficulties. Embryonic cells are so sought after because they can transform into any cell in the body. Although scientists have been…
