Mutations The replication process of DNA is extremely accurate; however, errors can occur when  nucleotide bases between DNA strands are occasionally paired incorrectly. In addition,  errors in DNA molecules may arise as a result of exposure to radiation (such as  ultraviolet or X-ray) or various reactive chemicals. When errors occur, repair  mechanisms are available to make corrections. If a DNA error is not repaired, it becomes a mutation. A  mutation  is any sequence of  nucleotides in a DNA molecule that does not exactly match the original DNA molecule
