Which of the following solves the problem of shortening of chromosomes in each cell cycle?

(a) DNA ligase

(b) Endonuclease

(c) Telomerase

(d) RNA polymerase

I got this question by my school teacher while I was bunking the class.

This intriguing question comes from RNA-Dependent Synthesis of RNA and DNA in portion DNA, RNA and Protein Metabolism of Biochemistry

Best answer
The correct choice is (c) Telomerase

For explanation I would say: Telomerase adds telomeres to chromosome ends and solves the problem of chromosomes shortening.
