Question

A research laboratory uses a cancer cell line that has undergone thousands of cell cycle divisions in the laboratory without any change in the length of its chromosomes. The cancer cell line is therefore likely to express high levels of RNA polymerase. Very low levels of telomerase. High levels of telomerase. DNA polymerases with high fidelity. High levels of ligase activity.
