Researchers Find "Immortality" Enzyme in Cancer Cells Cancer
... The telomere is made up of DNA segments that help control the accuracy of genetic reproduction when a cell divides to create a new cell. In cancer cells, it is thought that the telomere does not erode with each cell division, thus enabling cancer cells, in a sense, to be "immortal." Telomeres in can ...
