Telomerase

It's Telomerase. During normal DNA replication, the ends of the chromosome (telomeres) get cut off and over time the cell dies. In cancer cells, telomerase is over active and adds on to the telomeres, allowing the chromosome to continue replicating.

I think it is Morphogen but I could be wrong
