Subunit family spreading in multiple LCR22' blocks is often adjacent to Alu repeats. (A) The SD subunits were assigned to different layers of circles, whereas the numbers represent the total blocks in which a subunit family has one or more members. For example, a subunit family is given 3 if its members are found in 3 of the 8 blocks, and consequently all subunits of this family will be drawn in the circle labeled with "3". (B) Relationship between selected sequence features and block occupancy for SD subunits. The x-axis describes the number of blocks a subunit family occupies (A). The y-axis shows the percentage of subunit endpoints with a given sequence feature. No subunit family was found in and only in five blocks.
