gene splicing of human dna
Gene splicing first came to worldwide attention in 1973 with the creation of the first genetically engineered organism. Definition of Gene Splicing Gene splicing is the procedure where pieces of DNA are cut up and spliced together to form recombinant DNA. The DNA fragments usually come from different organisms. The DNA molecules are not cut by a physical pair of scissors; the process is enzymatic with the target DNA being chemically cut by restriction enzymes.
