Abstract |
The ends of linear chromosomes are constituted of repetitive DNA sequences called telomeres. Telomeres, nearby regions called subtelomeres, and their associated factors prevent chromosome erosion over cycles of DNA replication and prevent chromosome ends from being recognized as DNA double-strand breaks (DSBs). This raises the question of how cells repair DSBs that actually occur near chromosome ends. One approach is to edit the genome and engineer cells harboring inducible DSB sites within the subtelomeric region of different chromosome ends. This provides a reductionist and tractable genetic model system in which mechanisms mediating repair can be dissected via genetics, molecular biology, and microscopy tools. |
