Cloning is not all same as genetic engineering.

http://en.wikipedia.org/wiki/Cloning
Cloning in biology is the process of producing similarpopulations of genetically identical individuals that occurs in naturewhen organisms such as bacteria, insects or plants reproduce asexually. Cloning in biotechnology 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.

Genetic engineering, also called genetic modification, is the human manipulation of an organism's genetic material in a way that does not occur under natural conditions. It involves the use of recombinant DNA techniques, but does not include traditional animal and plant breeding or mutagenesis. Any organism that is generated using these techniques is considered to be a genetically modified organism. The first organisms genetically engineered were bacteria in 1973 and then mice in 1974. Insulin producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994 refers to processes used to create copies of
