From: Eukaryotic genomes may exhibit up to 10 generic classes of gene promoters
Ten classes of promoters and their representative patterns. Each promoter pattern is composed of vertically aligned clusters of Kappa IC (y-axis) and GC% (x-axis) values. The center of weight for each pattern is represented by a black circle. These representative promoter patterns are shown in the following sections as follows: (A) AT-based, (B) CG-based, (C) ATCG-compact, (D) ATCG-balanced, (E) ATCG-middle, (F) ATCG-less, (G) AT-less, (H) CG-spike, (I) CG-less and (J) AT-spike.
