recombinant DNA technology

a mixture of technologies developed in the 1970s that include (a) specific cleavage of DNA by restriction endonucleases; (b) nucleic acid hybridization which makes it possible to identify specific sequences of DNA or RNA; (c) DNA cloning whereby a specific DNA fragment is integrated (spliced) into a rapidly replicating, high yielding genetic element (plasmid or virus) so that it can be amplified in bacteria or yeast; (d) DNA sequencing of the nucleotides in a cloned DNA fragment.
