Explanation
Genetically modifying an organism requires all three steps: identifying the DNA carrying the desirable genes, introducing that DNA into the host, and maintaining the introduced DNA in the host and transferring it to its progeny. Each is a basic, indispensable step of the standard rDNA procedure. Hence 1, 2 and 3.
