The process of changing or altering the genes may be summarized in four basic steps, which among the following steps come first?
Isolate the DNA from the cell and identify the target part of the DNA
Cut the specific part of the DNA through a special enzyme
Combine the DNA from two different sources
Introduce the new formed DNA to the host cell
