Modular repeat composition of C2MC. A) The basic repeat in C2MC is MSHORT1: this is a 296 nt unit, which contains a 75 nt 3' portion of a rodent B1F3 element and a ~83 nt pre-miRNA gene consensus, which overlapped with an annotation of two self-complementary microsatellites. B) An array of ten MSHORT1 copies (C1 to C10) forms a 2,5 Kb unit called MLONG1, which contains 3 miRNA genes (red) and 6 B1F3 elements (green). C) The center of C2MC is generated by tandem duplication of MLONG1 elements; the flanks of C2MC contain less regularly spaced MSHORT1 units (pink).
