Analysis of monomer subtype composition in L1 promoters shows three position preference modes. a Distribution of monomer count per promoter of all three types. Promoters were generated by merging monomers within 20bp of each other. b Schematic diagram of ordering monomers based on their placement with respect to the orientation and ORF. c Three modes of monomer position preference. The distribution of monomer count for Type A promoters was used (left panel). Three A subtypes were chosen to represent distinct position preference modes, respectively. The three modes are: (1) Subtype 1 corresponding to the intermediate region mode, (2) Subtype 2 corresponding to the terminus region mode, and (3) Subtype 9 corresponding to the no preference mode
