Mutations are changes to the base sequence of DNA that may lead to different sequence of amino acids and therefore a potentially different protein, which may or may not be functional, depending on the type of mutation.

Mutations may be neutral, leading to no change in the protein or can cause a change on the protein - these changes can be detrimental (e.g. in genetic diseases) or beneficial (e.g. in evolution).
