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.
- Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame.
