The effects of ageing on Alzheimer's Disease
When our cells become faulty they are repaired by the DNA repair mechanism and therefore it is obvious that a cell whose DNA repair enzymes are in working condition lives longer (Hart & Setlow, 1974).However, the most important and relevant factor to the process of ageing are genetic processes. The most important example of this is Progeria, where genetic mutations rapidly enhance the rate of ageing in an individual. Mutant gene studies and study of long living organisms has provided
