Question

How often do mutations occur?

Answer 1

Gene Mutations 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

These changes can also be caused by environmental factors such as ultraviolet radiation from the sun or can occur if a mistake is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed on to the next generation.
