Examples

In some cases, a replicative transposition is observed in which a transposon replicates itself to a new target site (e.g. helitron (biology) ). Source: Internet

It is not yet understood why these elements are spliced, whether by chance, or by some preferential action by the transposon. Source: Internet

Sometimes the insertion of a TE into a gene can disrupt that gene's function in a reversible manner, in a process called insertional mutagenesis ; transposase-mediated excision of the DNA transposon restores gene function. Source: Internet

This step cuts out the DNA transposon, which is then ligated into a new target site; the process involves activity of a DNA polymerase that fills in gaps and of a DNA ligase that closes the sugar-phosphate backbone. Source: Internet

Such an insertion could intronize the transposon without disrupting the coding sequence when a transposon inserts into the sequence AGGT, resulting in the duplication of this sequence on each side of the transposon. Source: Internet
