CloningCloning is the process of making a is the process of making a genetically identical organism or cell genetically identical organism or cell through nonsexual means. through nonsexual means.
3 main types of cloning technology:3 main types of cloning technology:
1.1. Reproductive cloningReproductive cloning - Technology used to generate - Technology used to generate
an animal that has the same an animal that has the same nuclear DNA as another nuclear DNA as another currently or previously currently or previously existing animal. existing animal.
22. DNA cloning. DNA cloning aka: recombinant DNA technology, molecular aka: recombinant DNA technology, molecular
cloning, or gene cloning cloning, or gene cloning the transfer of a DNA fragment of interest from one the transfer of a DNA fragment of interest from one
organism into a segment of DNA that can copy itself. organism into a segment of DNA that can copy itself. (Plasmid)(Plasmid)
3. Therapeutic Cloning3. Therapeutic Cloning Aka: embryo cloning Aka: embryo cloning The production of human embryos for use in The production of human embryos for use in
research. research. The goal of this process is not to create The goal of this process is not to create
cloned human beings, but rather to harvest cloned human beings, but rather to harvest stem cells that can be used to study human stem cells that can be used to study human development and to treat disease. development and to treat disease.
