What is telomerase?

Question

What is telomerase?

Quizplus · Accepted Answer

Telomerase is an enzyme that adds nucleotide bases to the end of chromosomes, called telomeres. Telomeres shorten during each round of cell division, so telomerase helps to prevent the loss of genetic information and maintain the stability of chromosomes.

Answer: A, B, D, E
 None of the other answer choices accurately describe telomerase. A is incorrect because there is no evidence that telomerase is found in abundance on colon cancer cells specifically. B is incorrect because telomerase does not inhibit the formation of blood vessels, but rather is involved in cell division. D is incorrect because telomerase is not involved in the telophase stage of mitosis. E is partially incorrect because while RNA synthesis involves nucleotide bases, telomerase specifically adds bases to the ends of chromosomes, not involved in RNA synthesis.
