Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues. Gene cloning, also known as DNA cloning, is a very different process from reproductive and therapeutic cloning. Reproductive and therapeutic cloning share many of the same techniques, but are done for different ...

Many people first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Artificial cloning technologies have been around for much longer than Dolly, though. There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer. 1. Artificial Embryo Twinning

Before cloning, we have to create recombinant DNA. ... and it can replicate using the new host's DNA polymerase enzyme and make multiple identical copies and this is how gene cloning is performed.

en.wikipedia.org/wiki/Cloning

Cloning is the process of producing genetically identical individuals of an organism either naturally or artificially. In nature, many organisms produce clones through asexual reproduction. Cloning in biotechnology refers to the process of creating clones of organisms or copies of cells or DNA fragments (molecular cloning).

Reproductive cloning. Reproductive cloning involves the implantation of a cloned embryo into a real or an artificial uterus.The embryo develops into a fetus that is then carried to term. Reproductive cloning experiments were performed for more than 40 years through the process of embryo splitting, in which a single early-stage two-cell embryo is manually divided into two individual cells and ...

Reproductive cloning is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. It is accomplished using a process called somatic cell nuclear transfer. In 1996, Scottish researchers announced that they had successfully cloned the first mammal, a sheep who came to be known as Dolly.

Cloning. A clone is a genetically identical copy of an organism, and it may be naturally occurring or created in the lab. Through the process of asexual reproduction, organisms such as bacteria (and some plants) create offspring that are genetically identical to the parent.

The success rate in cloning is quite low: most embryos fail to develop, and many pregnancies end in miscarriage. Current efforts at human cloning are focused on creating embryonic stem cells for research and medicine, as described above. However, many feel that this type of therapeutic cloning comes dangerously close to human reproductive cloning.

Much cloning research is actually focused on creating embryonic stem cells from the cloned embryo, rather than growing cloned humans (this field is called therapeutic cloning and is less ...

How Does Cloning Work? ... Cloning may invoke an image of an army of identical cows or sheep churned out factory-style, but in actuality, the process is much more laborious.
