The is about genetic manipulation, and the first example is in 1972 Paul Berg made the first man made recombinant DNA by using restriction enzymes and ligase. After that, there have been several experiments using recombinant DNA where a retrovirus would be stripped of its infectious genes and replaced with a desired gene and then injected into the body either directly or through cultured cell, trying to cure various diseases through gene therapy such as SCID, hemophilia, cystic fibrosis, and cancer. Genetic engineering has very unnecessarily polarized its proponents and radical environmentalists, stemming from the issue of agricultural genetic engineering. Ridley explains the possibilities of human cloning with genetic improvement through the use of embryonic stem cells and recombinant DNA.
