Which theory of aging suggests that human cells have a built-in time limit to their reproduction and that they are no longer able to divide after a certain time?

The correct answer is: Genetic preprogramming theory.

Explanation:

The genetic preprogramming theory is a theory of aging that states that human longevity is directly affected by the genes that we inherit from our parents. Thus, our lifespan is greatly determined since we are born.

Programming theories of aging propose that human longetivity is the consequence of certain genes turning off and on and certain cells have a predetermined built-in time limit to their reproduction and after a period of time they are no longer able to divide.

In conclusion, the theory of aging that support that approach to human longetivity and cell reproduction is called genetic preprogramming theory.
