Aresearcher studies normal human fibroblast cells. they can be maintained in culture but die off after about 30 cell generations. unexpectedly, a colony of cells continues to survive and divide past 30 generations. which scenario is most likely true for these cells?

The telomerase gene is being expressed.

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.
