A group of elderly residents were commenting on how many cell functions decline with age
One resident commented that many of his friends who lived under large electromagnetic towers seemed to experience aging at an accelerated rate in comparison with residents who lived nearby in lakefront housing. This observation is the basis for which theory on aging?
A) Theories of genetic influences
B) Programmed cell receptor theories
C) Insufficient telomerase enzyme theory
D) Error theory associated with DNA damage
Ans: D
Feedback:
Error theory suggests that aging results from DNA mutation or faulty repair. Another group of theories of aging focuses on programmed cell changes with genetic influences that systematically cause cell senescence. Elimination of receptor sites is not part of aging theory. Telomerase enzyme is thought to reduce the shortening of the chromosomes and loss of telomere DNA with each cell replication.
