3 types of point mutations:
- Nonsense,
- Misense,
- Silent.
Nonsense and misense: Causes different amino acid to be produced.
Therefore chain is affected. Nonsense codes for STOP.
Silent: Same amino acid is produced.
Therefore chain is unaffected.
Insertion/deletion: Causes frameshift.
All affected from mutation onwards.
Causes different 3D structure.
