Answer:

The telomerase gene is being expressed.

Step-by-step explanation:

Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells.

Independent telomerase functions can be also involved in cell cycle regulation.
