Explanation:
Detailed explanation-1: -Genetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.
Detailed explanation-2: -These mutations occur as a result of DNA copying errors made when normal cells divide. What causes such random DNA copying errors? Human cells are constantly regenerating.
