The target sequences for two independent insertions of the transposable element Tc1 from Caenorhabditis elegans show homology. Because both insertions are at palindromic TA/AT sequences, the exact boundaries of Tc1 cannot be distinguished; Tc1 could be 1610 bp and flanked by a 2-bp duplication of the target site or it could be 1612 bp and without target site duplication. The latter possibility implies a novel manner for insertion of a transposable element.
来自秀丽隐杆线虫的转座元件Tc1的两个独立插入的靶序列显示出同源性。由于这两个插入都位于回文TA/AT序列处,因此无法区分Tc1的确切边界;Tc1可能为1610 bp,并由靶位点的2 bp重复序列侧翼包围,或者它可能为1612 bp且没有靶位点重复。后一种可能性暗示了转座元件插入的一种新方式。
