When would a mutation in a DNA sequence most likely occur

Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

Hope this helps

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
