recombine DNA
B
cut DNA
C
separate DNA fragments
D
extract DNA
2) On an electrophoresis gel, band B is closer to the postive end of the gel thatn is band A
A
Band A is smaller than Band B
B
Band B is more negatively charged than Band A
C
Band B moved faster than Band A
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

change the color of the DNA
B
convert the DNA into a gel
C
cut the DNA into fragments
D
produce longer sections of DNA
4) For centuries certain animals have been crossed to produce offspring that have desirable qualities. This technique of producing organisms with specific qualities is known as

selective breeding
B
gene replication
C
natural selection
D
random mutations
5) The Human Genome Project is an attempt to
A
make a DNA fingerprint of every person's DNA
B
cure human diseases
C
identify alleles in human DNA that recessive
D
sequence all human DNA
6) If a gene is inserted into the DNA of a bacterial cell, every cell produced by that cell will have
A
DNA that is different from that of the other cells produced
B
a 50% chance of having a copy of the inserted gene
C

genetic engineering
C
direct harvesting

human DNA always promotes human survival so there is no need to alter it
