C
recombine DNA
D
separate DNA fragments
2) On an electrophoresis gel, band B is closer to the postive end of the gel thatn is band A
A
Band B moved faster than Band A
B
Band B is more negatively charged than Band A
C
Band A is smaller than Band B
D
Band B consists of larger DNA fragments than does Band A
3) In preparation for an electrophoresis procedure, enzymes are added to DNA in order to

random mutations
B
selective breeding
C
natural selection
D
gene replication

meiosis
