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: -While mutations always change the DNA sequence, they do not always cause a change in the resulting protein or an obvious effect on the organism.

Detailed explanation-3: -There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu—–> Val which causes sickle-cell disease.
