When a biological vector is used, which process must take place before recombinant dna can be placed in the host cell?

The appropriate response is gene isolation. The absence of interbreeding or minimal hereditary blending between living beings of similar species. Supplement. Hereditary confinement might be the consequence of geographic disengagement or of other segregation systems that anticipated effective generation.

Before insertion of recombinant DNA into the host cell, gene isolation should be performed, in order to integrate the gene of the desired characteristic, to the gene of the host. This is followed by gene targeting and transformation. Restriction enzymes are used to cut the desired gene sequences.
