1. Which of the following statements most accurately conveys an aspect of the error

theory of aging?

A) Perpetuation of DNA mutations results in organ and system malfunction.

B) Age-related dysfunction of organs, tissues, and body systems results in mutation

of body DNA.

C) The number of cell divisions is genetically predetermined.

D) Errors in the function of various organs contribute to changes in the genetic code

of various body cells.

Ans: A

Feedback:

The error theory of aging proposes that genetic mutations are perpetuated through the

aging process, resulting in organ malfunction and eventual decline in body function.

Organ malfunction results from, but does not cause, the genetic mutations in question.

A genetic predetermination of the number of cell divisions is associated with the

programmed theory of aging.

2. The error theory of aging proposes a cause-and-effect relationship between the genetic

activity of body cells and the effects of aging. Place the following steps in the error

theory of aging in the correct chronological order. Use all the options.

A) Organ, tissue, and system malfunction

B) Perpetuation of mutation during cell divisions

C) DNA mutation

D) Overall decline in body functions

E) Decline in body functions

Ans: C, B, E, A, D

Feedback:

The error theory of aging proposes that DNA mutations occur on a single-cell level and

are perpetuated in subsequent cell divisions. The overall number of mutant cells in the

body increases and causes deleterious effects on tissues and systems and eventual

decline in body function.
