It is only at the very end of a fragmented chromosome that euchromatic DNA can contain telomere-specific features. It appears that these fragments, mostly from UTRs, are passively transported to non-telomeric heterochromatin regions rather than actively translocated . Furthermore, they are found in these regions. Each newly transposable element is twisted such that its 5' end coincides with the chromosome end, because telomeric elements are retrotranscribed to chromosome ends. These telomere ends are dynamic, just as the ones maintained by telomerase .
