The process in which strands of DNA are cut into pieces and spliced together is referred to as gene splicing. The strands of DNA are chemically cut using restriction enzymes. Restriction enzymes are used to cut specific base pair sequences of DNA only. There are thousands of these enzymes since strands of DNA vary. The restriction enzyme cuts the DNA at the specific base pair location which secludes that particular strand of DNA. They then add another DNA sequence to this strand and create the protein product of the new gene. The DNA strands that are combined are usually from various organisms.
Herb Boyer and Stanley Cohen were the men who invented gene splicing in 1973. They placed a gene from a toad called a Xenopus into bacterial DNA. A year earlier a scientist named Paul Berg actually used gene splicing to create DNA molecules. He was actually the first scientist to splice together DNA strands from two different organisms together. His research made the discovery of restriction enzymes by Daniel Nathans and Hamilton Othanel Smith possible.
