telomere maintenance via telomere trimming
telomere maintenance via telomere trimming
"A process that contributes to the maintenance of proper telomeric length and structure via the activation of telomere shortening pathways that compensate telomerase-dependent excessive telomere elongation. Telomere attrition is mediated by a mechanism which involves the generation of single-stranded C-rich telomeric DNA, and the formation and removal of double-stranded telomeric circular DNA (T-circles). Telomere trimming is an independent pathway to recombination-mediated telomere elongation and the well-documented gradual telomere attrition that accompanies cellular replication."
