Telomere damage induces internal loops that generate telomeric circles

Extrachromosomal circular DNA made of telomeric repeats have been found to have an effect on telomere maintenance. By combining electron microscopy with a telomere purification procedure the authors identify damage-induced i-loops as a key intermediate in telomere circle formation.
