O no, you are not right. The division of a yeast ( S.cerevisiae) cell
budding give rise to two cells which are identifiable, that is, the mother
cell from which the bud arose, and the daughter cell which developed
from the bud.
Therefore, yeast cell (S.c.) produce a finite number of daughters during
their life span, which are elaborated on the surface of mother cell as a
bud.
The number of buds produced by mother, one during each cell division
cycle, is the metric of the life span and as I sad before is finite (26-30
bud).
