    Résumé

    The DNA sequence spanning coordinates 9.9 to 16.4 kilobases of the lactose transposon Tn951 ( Cornelis et al., Mol. Gen. Genet. 160:215-224, 1978) constitutes a transposable element by itself. Unlike Tn951 ( Cornelis et al., Mol. Gen. Genet. 184:241-248, 1981), this element, called Tn2501 , transposes in the absence of any other transposon. Transposition of Tn2501 proceeds through transient cointegration and duplicates 5 base pairs of host DNA. Tn2501 is flanked by nearly perfect inverted repeats (44 of 48), related to the inverted repeats of Tn21 ( Zheng et al., Nucleic Acids Res. 9:6265-6278, 1982). Unlike Tn21 , Tn2501 does not confer mercury resistance.
