Cloning

In my research I focused on Cloning. Cloning was first invented by a man named Hans Spemann. He did cloning with differentiated cells by nuclear transfer. This was founded in 1938. Also in 2001, the first animal was cloned. It was a baby bull gaur named Noah. This shows that we can save endangered species. Cloning is the process of making a genetically identical organism through nonsexual means. It Has been used for many years to produce plants. Their are many different types of cloning but a common one would be reproductive cloning. This has to do with people, animals, and plants. Three common types of cloning technologies are recombinant DNA technology or DNA cloning, reproductive cloning, and therapeutic cloning. Recombinant DNA refers to the transfer of a DNA fragment of interest from one organism to a self-replicating genetic element such as a bacterial plasmid.

Therapeutic Cloning is the production of human embryo for the use of research. The goal of the process is not to create cloned human beings, but rather to harvest stem cells that can be used to study human development and to treat disease. This is very expensive and highly inefficient. More than 90% temps fail. Cloning animals is easier but they seem to die young or at an early age. I believe this was recreated for a new way of life. Helping families have a child that they lost or to save endangered species. I could not just find one reason why this was created but he had good intentions.
