Cloning Technology

Cloning technology is a very arguable subject, although most people don't know enough about it to make an informed decision. First, I will define why cloning was created and what its purpose was. Then, I will describe the types of cloning. Next, I will walk you through the cloning process. Lastly, I will then state the facts on cloning that scientists have discovered.

Cloning was developed as a way to help those suffering from terminal illnesses such as Alzheimer’s and Parkinson’s diseases. Cloning embryonic stem cells could be used to grow new organs and tissues that can be used in transplants to replace damaged ones including new skin for burned victims. This also extends to brain cells for those who are brain damaged or have suffered strokes, spinal cords for paraplegics, new hearts, livers, lungs and kidneys. As mentioned before, conditions such as Alzheimer’s, Parkinson’s and other degenerative diseases could be cured and eradicated if cloning and its technology were not banned. Cloning can also allow for genetic diseases to be discovered, targeted and eradicated.

There are three types of cloning methods that are contained within the genetic engineering of the cloning process.

Reproductive: This type uses an animal in existence with the exact DNA; the procedure is called ‘somatic cell nuclear transfer’. Scientist transfer from the nucleus, genetic material of the donor adult cell to the egg, where its nucleus genetic material is replaced. To aid cell division, the egg must be constantly exposed to an electric current or chemicals that will help in the process. After a considerable amount of time has lapsed, it is then transferred to a female uterus of that particular animal breed, where it will take form and develop until it is ready to be born.

Recombinant DNA Technology: labeled as ‘molecular cloning’, or 'DNA/gene cloning', this procedure refers to the transferring of a...
