DNA molecules face change in its nucleotide sequence that creates a big change at the end result known as protein. These changes are called mutations that have different types.

  • Germline mutations occur in gametes. Somatic mutations occur in other body cells.
  • Chromosomal alterations are mutations that change chromosome structure.
  • Point mutations change a single nucleotide.
