WebJul 19, 2024 · The sequence within these flanking direct repeats (FDRs) is distinctive for each copy of the transposable element, but the size of the FDR is characteristic of a particular family of transposable elements. Some families of transposable elements have FDRs as short as 4 bp and other families have FDRs as long as 12 bp. WebSep 13, 2024 · Their transfer starts by the excision from the chromosome by a site-specific recombinase (usually tyrosine or serine integrases) that recognizes specific direct repeat sequences ( att sites) flanking the element. These direct repeats are the result of the action of the recombinase during the element insertion.

WebFlanking direct repeats are created in the process of transposition. The staggered cuts made in the target DNA leave behind flanking direct repeats on either side. NOT apart of transposon.
