Fig. 5From: Single-molecule analysis of subtelomeres and telomeres in Alternative Lengthening of Telomeres (ALT) cellsPunctate and Extrachromosomal Telomeres. Representative examples of raw images with the DNA backbone blue, and both the labeled subtelomeric Nt.BspQI sites and the telomere (TTAGGG) n tracts are green. a Examples of end telomeres with punctate (TTAGGG) n tracts. The intensity of these telomere tracts is decreased and shown below the full molecule. b Examples of Extrachromosomal telomeres, many of which display punctate (TTAGGG) n tractsBack to article page
