A DNA molecule produced by combining DNA from different sources is known as?

It is recombinant DNA. A hybrid is formed when DNA STRANDS from two different sources are combined. Meaning that one strand of the double-helix is from one source, and the other is from another source. A hybrid could also mean a molecule containing DNA from one source and RNA from another source. Recombination is the combining of BOTH strands of DNA from one source to BOTH strands of DNA from another source.
