Table 1. Simulated heterogenous regulatory sequence classes with multiple regulatory grammars that can distinguish one class from another.

	Regulatory grammars in sequence type 1	Regulatory grammars sequence type 2
Heterogeneous Regulatory Sequence Class 1	homotypic cluster 1, homotypic cluster 2	homotypic cluster 4, heterotypic cluster 4
Heterogeneous Regulatory Sequence Class 2	heterotypic cluster 1, heterotypic cluster 2	homotypic cluster 5, enhanceosome 1
Heterogeneous Regulatory Sequence Class 3	homotypic cluster 3, heterotypic cluster 3	heterotypic cluster 5, enhanceosome 2
