| | Variant insertion element IS1 generates 8-base pair duplications of the target sequence (Site not responding. Last check: 2007-10-08) |
 | | For example, the bacterial insertion sequence IS1, or the IS1-flanked transposon Tn9, generates 9-base pair (bp) repeats during either transposition or cointegration |
 | | All the transposable elements so far sequenced are characterized by the presence at their ends, of a perfect, or near-perfect, inverted repeat sequence, which is |
 | | We now report that it generates 8-bp duplications of the target sequence, a finding which confirms the importance of the inverted repeat for transposition and which, because one end only of the IS1 is changed, has implications for the mechanism of transposition by IS1. |
