Issues with Animal Cloning
The theory of being able to make a genetic copy (a clone) of another animal has been around for quite a while. But animal cloning has been a scientific breakthrough only in recent years. Through cloning and genetic engineering, scientists have been able to perform incredible medical procedures that could one day help diseased people all over the world. There are many steps involved in cloning, and many precautions must be used. Scientists have found many useful benefits to animal cloning in many areas of science, and these may one day help mankind in the future.
In order for animal cloning to be successful, many steps are necessary. There are three common ways of cloning animals. One way is by separating the embryo. This involves taking out a fertilized ovum, waiting until a cell cultivates into four cells, separating these cells, then putting the ovum back into the animal. Each of the cells has the exact same DNA. Another way of cloning animals is nuclear transplantation (taking the cell from a fertilized ovum). This is done by taking out a fertilized ovum from an animal when nuclear splitting starts, then by using enzymes, the nucleus will be cut one by one, then a cell is taken out of an unfertilized ovum that came from a different animal and a cell from the fertilized ovum is put in to replace it, then an electrical shock is given to the unfertilized ovum so that the cell and unfertilized ovum come together to become a fertilized ovum. This ovum is put into another one of the animal so that it can give birth to the newly fertilized egg. Another common method of cloning is done by taking cells from parts of the body. First, a cell is taken from an animal, then cell is cultivated so it will become active again, then an unfertilized ovum is prepared, then a cell is taken from it and replaced by the original cell from the animal being cloned. By using electrical shock the cell and ovum come together to become fertilized, making a cloned egg. This cloned egg is inserted into an unfertilized ovum to give birth to the clone. As it can be seen, nuclear transplantation and taking cells from parts of the...
