Twins? Or is it clones? It has been known that identical twins are natural clones. The question is, what is cloning? Cloning is the process of making a genetically identical organism through the use of a DNA sample. There are three different types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning. Dolly, the sheep, was the first mammal to have been successfully cloned from an adult cell. There is a specific procedure that has to be followed for a clone to be made. Over the course of time, scientists have been able to clone many different types of animals. There are some benefits that come along from animal cloning that can be very useful to us, humans.
In biology, cloning means making identical duplications of genes, fragments of DNA molecules, or cells. There are three different types of artificial cloning. Gene cloning produces copies of genes or pieces of DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning produces embryonic stem cells for experiments directed at creating tissues to replace injured or diseased tissues. All these types of cloning are made for different reasons. To clone a mammal, scientists change the DNA between cells by doing a nuclear transfer. First, an unfertilized egg is taken from the animal and the egg’s nucleus is removed. Then the nucleus of a cell from the animal to be cloned is implanted into the egg. The egg is stimulated and if the procedure is successful, the egg will begin…
