As part of a clinical research study, the characteristic of neoplastic and normal cells are being analyzed in culture. It is observed that neoplastic cell division is aided by an enzyme that repairs progressive chromosomal shortening, a process that does not occur in normal cells. Due to lack o chromosomal shortening, these neoplastic cells divide more rapidly than do normal cells. Which of the following enzymes is most likely involved?
a. Protein Kinase
b. Reverse transcriptase
c. Telomerase
d. DNA polymerase
e. Topoisomerase
