A) Telomerase is bound to telomeres,and thus blocks the repair system from binding to telomeres.
B) Telomerase catalyzes reactions that interfere with the repair system.
C) DNA polymerase blocks the repair system from accessing the telomere DNA.
D) Telomeres are at the end of the chromosome,and DNA is replicated in only one direction.
E) Protective proteins bind to telomeres,and therefore the repair system does not recognize telomeres as breaks.
