Question

What factors may contribute to aging?

Answer 1

Answer:

The factor that contributes to aging is: A Cells stop dividing after 50 divisions.

Explanation:

• Normally after 40 to 50 divisions the cells stops dividing because they had already lost too much DNA for other divisions.

• So they eventually die, making the appearance like an aged person in any individual.

• As DNA is copied in every cell division process, they tend to loose small part of telomeres in each transfer process.

• Hence, after 50 divisions these cells fails to divide resulting in aging.
