Mis-Sense
Change in base pair
Can code for a different amino acid
Causes the protein to become disfunctional
Deletions
Deletes a base
All subsequent bases are shifted to right
All codons change
If the deletion is at the start it can cause huge changes
If at the end not as many changes
Causes protein to become disfunctional
Chromosome disjunction
Chromosomes fail to spearate during meiosis I or Meiosis II
Protein Synthesis
Transcription
Copy out of nucleus
Translation
