Figure 4.—

Location of mobile element insertions in the rDNA unit. Abbreviations within the rDNA transcription unit are as described in Figure 1. A small region of the 28S gene, which contains many insertion classes, is magnified above this repeat. Arrows indicate the insertion site of the various elements based on their 3′ junction with the gene. The current known distribution of each element is also shown. For more detailed descriptions of these elements see Eickbush (2002), Kojima and Fujiwara (2003), and Kojima et al. (2006).
