How do cancer cells use the enzyme telomerase?

Answered

Cancer cells often use the enzyme telomerase to maintain their telomere length, allowing them to bypass the normal limit on the number of times they can divide. In most normal somatic cells, telomerase is inactive, and telomeres shorten with each cell division. However, in many cancer cells, telomerase is reactivated, which prevents telomere shortening and allows the cells to continue dividing indefinitely. This is one of the factors that contribute to the uncontrolled growth and immortality of cancer cells.
