What is telomere shortening associated with?

Correct Answer: changing
sleeping
reducing
aging

Explanation: Telomerase is not active in adult somatic cells. Adult somatic cells that undergo cell division continue to have their telomeres shortened. This essentially means that telomere shortening is associated with aging. In 2010, scientists found [1] that telomerase can reverse some age-related conditions in mice, and this may have potential in regenerative medicine.
