What is the effect of telomere caps on cancer cells?
rect Answer Repeated divisions
Clonal distinction
u Answered Limited mitosis
Mutation abilities
The presence of telomere caps gives cancer cells the ability to divide over and over again, thus
cancer cells have unlimited mitosis. Telomere caps do not give cells clonal distinction. Mutation
capability is a characteristic of cancer cells, but this property is not related to telomeres.
