Answer:
B) Telomerase is a ribonuclear protein containing a section of RNA complementary to the telomeres
C. telomerase is reactivated in cancer cells, contributing to their immortality
Explanation:
- Telomerase elongates telomere ends
- Telomerase binds to a RNA molecule containing a sequence complementary to the telomeric repeat.
- Telomerase is usually not active in somatic cells but is active in cancer cells- the protein acts to extend the shortened telomeres in these cells preventing them from dying
