molecular infedelity
- programmed sequence of events
- finite ability to reproduce
- degen w/i cells before they reached growth limit
what is the telometric theory
extension of hayflick limit
- telomeres are specialized DNA sequences at end of chromosomes
in normal process of DNA replicaiton:
- end of chromosome is not copied exactly
- leads to un-replicated gap
what are 5 factors that influence life expectancy
hereditary
dz processes
med treatment
lifestyle choices
nutrition
