What Property of Restriction Enzymes Allows DNA from Different Organisms

Multiple Choice

What property of restriction enzymes allows DNA from different organisms to be combined?

A) Restriction enzymes cut DNA randomly, so any DNAs might be combined.
B) Restriction enzymes cut only small transformable fragments, not large chromosomal DNA.
C) Because restriction enzymes are naturally found in bacteria, they cut all transformed DNA.
D) If the same restriction enzyme cuts two different DNAs, the ends are complementary.
