- 4. SLIDESMANIA Gene cloning • Molecularcloning, Recombinant DNA technology or DNA cloning • Gene cloning is the process of creating identical copies of a specific gene or DNA sequence. • Gene cloning is genetic engineering technique self replicates and generates a large number of identical copies of the particular gene.

SLIDESMANIA REPRODUCTIVE CLONING • Reproductive cloning- is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. • Dolly the sheep was the first mammal cloned from adult DNA the process is called “Somatic cell nuclear transfer” (SCNT). • Somatic cell nuclear transfer (SCNT) - in this process the genetic material from an adult cell (any type - skin,blood,etc) is traansferred to an egg that has had its nucleus removed. It is then stimulated to produce an embryo by chemical or electric current.

- 9. SLIDESMANIA THERAPEUTIC CLONING •Therapeutic cloning, alsocalled “embryo cloning” is the production of embryos for use in research. •Therapeutic cloning use cloned embryos for the purpose of extracting stem cells from them without ever implanting the embryos in a womb •The goal of this 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.
