Which of the following statements concerning the enzyme, telomerase, is true? (Select all that apply.) A) Telomerase removes tel
omeres, making DNA replication more efficient. B) Telomerase is a ribonuclear protein containing a section of RNA complementary to the telomere. C) Telomerase is reactivated in cancer cells, contributing to their immortality. D) If telomerase was inactivated DNA synthesis would stop.
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
