Fig. 1.

Characteristics of Hsmar1 mariner transposons. “Full-length” Hsmar1, “gappy” Hsmar1, and MITEs (Miniature Inverted Repeat Transposable Elements) contain two inverted terminal repeat (ITR) sequences (red triangles). “Solo” inverted repeats contain one ITR linked to a truncated Hsmar1 sequence or not. In each category, up to three mismatches were allowed in the flanking ITR sequences (“core” motif: 5’-GGTGCAAAAGTAATTGCGG-3’). Histogram shows the length distribution of MITE sequences with a median size of 68 bp. Only ITRs within 500 bp were considered to identify MITEs. The number of cases (n) is shown on the left.
