Telomeres: Structures in need of unwinding

Abstract excerpt

Telomeres protect the ends of eukaryotic chromosomes from being recognized and processed as double strand breaks. In most organisms, telomeric DNA is highly repetitive with a high GC-content. Moreover, the G residues are concentrated in the strand running 3'-5' from the end of the chromosome towards its center. This G-rich strand is extended to form a 3' single-stranded tail that can form unusual secondary...
