The best answer is A.

A restriction enzyme is an enzyme that catalyzes the cleavage of DNA after recognizing a specific sequence of DNA.

Restriction enzymes are proteins produced by bacteria that cut  DNA at specific sites. These enzymes are used by bacteria to defend against bacterial viruses known as bacteriophages.  When a phage infects a bacteria, it inserts  its DNA into the bacteria so as to be replicated.

The restriction enzyme thwarts the replication of the phage DNA  by cutting it into many pieces. These enzymes  have been isolated from bacteria by scientists and used as indispensable tools in recombinant DNA technology.

The INDEPENDENT VARIABLE:
klemol [59]

Answer:

B. Is what the scientists manipulate in the experiment.

Explanation:

The Independent variable is not dependent, or doesn't rely, on another variable in the experiment. So, it would make the most sense that they would manipulate the Independent so that they can watch and see how the dependent variable reacts to the manipulation, or the change, in the independent variable.
