Well, it shows up in the overwhelming majority of cancer cells, so the
presumption is that telomerase suppression interferes with the development
of cancer.

Yes, of course.

Possible, but alternative splicing is unusual with eukaryotic proteins.
>Could it be that telomerase is harmful in some tissues?
Yes, again.
