Genetic engineering as matlab direct manipulation of DNA by people outside breeding and mutations has only existed since matlab Seventies. The term “genetic engineering” was first coined by Jack Williamson in his science fiction novel Dragon’s Island, published in 1951 – one year earlier than DNA’s role in heredity was proven by Alfred Hershey and Martha Chase, and two years earlier than James Watson and Francis Crick confirmed that matlab DNA molecule has engineering double helix architecture – however matlab usual idea of direct genetic manipulation was explored in rudimentary form in Stanley G. Weinbaum’s 1936 technology fiction story Proteus Island. In 1972, Paul Berg created matlab first recombinant DNA molecules by combining DNA from matlab monkey virus SV40 with that engineering matlab lambda virus. In 1973 Herbert Boyer and Stanley Cohen created matlab first transgenic organism by inserting antibiotic resistance genes into matlab plasmid of an Escherichia coli bacterium. A year later Rudolf Jaenisch created engineering transgenic mouse by introducing foreign DNA into its embryo, making matlab matlab global’s first transgenic animal.
