Topic 2 Molecular Genetics: Mutation

Question 1

• When a mutation occurs, but the new codon still codes for the same amino acid, therefore the effect is “silenced”

Answer 1

1. Silent Mutations

Question 2

• The new codon codes for a stop codon

Answer 2

2. Nonsense Mutations

Question 3

• There is no change in protein function

Answer 3

3. Neutral Mutations

Question 4

• A new codon codes for a new amino acid → can have minor or fatal results (as in sickle cell anemia where glu → val)

Answer 4

4. Missense Mutations
