a. genes involved in related functions are arranged into a single operon with a promoter that activates all genes simultaneously.
b. the genes share a specific combination of control elements.
c. the genes are clustered as tandem repeats with a shared promoter region.
d. the genes are splice variants of a single sequence that is activated with a single promoter and then modified post-transcriptionally.
