Figure 4.

Duplicon organization of selected telomeres. The sequences are oriented with the telomeres at the left, with the distance from the end of the sequence to the start of the terminal repeat array indicated by the vertical arrow at the telomeric end of the sequence. The position and 5'-3' G-strand orientation of (TTAGGG)n elements are shown as black arrows. Note the co-localization of nearly all of the internal (TTAGGG)n islands with duplicon boundaries. The duplicon substructure for each of the 43 non-satellited telomeres is shown in Additional data files 6-47.
