Recombinant DNA. DNA that has been modified so that it contains genes from two different sources. Recombinant technology is often used to produce highly pure therapeutic drugs.

recombinant deoxyribonucleic acid – (i) molecules that are constructed outside living cells by joining natural or synthetic DNA segments to DNA molecules that can replicate in a living cell, or (ii) molecules that result from the replication of those described in (i) above

Procedure used to cut and join together DNA segments in a cell-free system (an environment outside a cell or organism). Under appropriate conditions, a recombinant DNA molecule can enter a cell and replicate there, either autonomously or after it has become integrated into a cellular chromosome.
