The clock at the end of every chromosome

To judge the epitalon claim, you first need the biology it rests on. This unit builds the telomere story from the ground up: why chromosome ends shorten with each division, what the Hayflick limit is, how telomerase can rebuild the caps, and where that enzyme is normally switched on.

None of this is about epitalon yet. It is the ruler you will use to measure the peptide’s central claim in the next unit.
