Answer 2

Answer:Recombinant DNA

Explanation:Recombinant DNA is basically a genetically modified DNA that is produced in the laboratory by bringing together different strands of DNA and causing them to bond in order to form a new genome or gene sequence and the whole procedure in performed in Vitro (in laboratory)

The DNA sequence is then inserted into the host to induce specific type of responses.
