B) A gene cloned from mice, rather than from humans can be used.
C) The bacterial protein has a different amino acid sequence that is more effective.
D) Larger quantities are available.

A) They break down all DNA molecules randomly.
B) They are used to break down the cell membrane of bacterial cell.
C) They break down all protein molecules inside the bacterial cell.
D) They cut DNA at specific sites.

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