A technique to confirm whether a particular candidate gene underlies a behavior is to alter the gene's expression. This can be done by
A) increasing gene activity by adding copies of the gene (knocking in).
B) increasing gene activity by disabling genes (knocking out).
C) increasing gene activity by microarray analysis.
D) all of the above.
