Review of Cloning

Cloning in terminology is derived from the Greek word for "trunk or branch", that referring to the process whereby a new plant can be created from a twig But in biology cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. The term also refers to the production of multiple copies of a product such as digital media or software. Who is dolly? Dolly, a female domestic sheep, is the first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer. She was cloned by colleagues at the Roslin Institute. She was born on 5 July 1996 and she lived until the age of six. The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific part of the body could recreate a whole individual. As the matter of facts Dolly is the first step of long way.
