b) a 50% chance of having a copy of the inserted gene
c) a copy of the inserted gene
d) a new type of DNA base

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
a) gene replication
b) natural selection
c) random mutations
d) selective breeding

In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
a) convert the DNA into a gel
b) cut the DNA into fragments
c) change the color of the DNA

Spider DNA is removed and inserted into a goat. Spider silk proteins are found in the goat's milk. This process is called
a) chromotography
b) direct harvesting
c) meiosis
d) genetic engineering

In the US, there has been relatively little experimentation involving the insertion of genes from other species in human DNA. One reason for the lack of these experiments is that
a) the subunits of human DNA are different from the DNA subunits of other species
b) there are many ethical questions to be answered
c) inserting foreign DNA into human DNA would require using techniques that are different
d) human DNA always promotes human survival so there is no need to alter it
