The mechanisms by which telomeres are distinguished from DNA double-strand breaks are poorly understood. Here we have defined the minimal requirements for the protection of telomeric DNA ends from nonhomologous end-joining (NHEJ). Neither long, single-stranded overhangs nor t loop formation is essential to prevent NHEJ-mediated ligation of telomeric ends in vitro. Instead, a tandem array of 12 ...

Abstract We report SOFIA/GREAT observations of high- J CO lines and [C ii ] the super star cluster candidate H72.97-69.39 in Large Magellanic Cloud (LMC), which is its very early formation stage. use our to determine if shocks are heating gas or photon-dominated regions (PDRs) being heated by local far-UV radiation. a PDR model shock whether arise from PDRs shocks. can reproduce observed emissi...
