Introduction of human cloning : 

Introduction of human cloning Pruduction of genetically identical individuals that have identical nuclear DNA. In biology-------Cloning is the process of production similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria,insects or plants reproduce asexually

Slide 4: 

In biotechnology------Cloning refers to process used to create copies of DNA fragment(molecular cloning),cells (cell cloning), or organisms (or) Cloning is a form of asexual reproduction whicch involve in creating genetically identical genes/cells,plants or animals

Slide 5: 

The term “clone” is derived from the greek word for “trunk, branch”, referring to the process whereby a new plant can be created from a twig

Different types of cloning : 

Different types of cloning Recombinant DNA cloning process also called “DNA cloning” or gene “gene cloning” transfer of DNA from one organism to a self-replicating genetic element DNA can then be propagated Since the 1970’s Method is used to copy genes for further information  Reproductive Cloning used to create a mammat that has the same DNA as another good example for this technique  dolly the sheep significant problems: more than 90% attempts fail Therapeutic Cloning also called “embryo cloning” production of human embryos for research purposes goal  to harvest stem cells of the embryo the extraction of stem cells from the embryo results in it’s destruction ethical questions about this method researches believe that these cells can be used to treat diseases
