Howy Jacobs: Molecular Biology and Ageing

Helsinki, Mörsky. 3.11.2005.

No mitochondria
Gradual fonctional decline
Death from ageing (degenerating process) or from other reasons: immortality not a practical issue

Genetically programmed? no
No advantage for the species in individuals not to age
What happens after reproduction is irrelevant for the species.

Repairing damage, efficiency
Irreplaceable cells:

Cancer, cell division

Diets help to span life time in mammals and other organisms and even yeasts.
Insuline -- growth
Stress -- food molecules broken by oxygen -- toxic by-products

Mitochondrial DNA. Only from the mother.
