cloning


Like stem cells, cloning is a rapidly advancing branch of biotechnology. Cloning is the creation of an organism genetically identical to the organism chosen to clone. Cloning can be done in many ways such as artificial embryo twinning . In this process an embryo is split just after fertilization much like identical twins. A more complex method is called somatic cell nuclear transfer. In this process the genetic material of a cell is removed and a cell with DNA from the animal to be cloned is fused to it thus injecting its genetic material. Now the cell is implanted into a surrogate mother and is born identical to the first organism. In the future scientists believe that cloning can be used to recreate cells lost from certain diseases. This has been done before in the Scottish sheep Dolly. The clone of Dolly was perfectly healthy. So, what do you think?
