Mutations

Question 1

Silent

Answer 1

Silent

If the mutation still produces the same amino acid it is
called a silent mutation.
Has no impact on the protein formed
This happens because the genetic code is
degenerate

Question 2

Nonsense

Answer 2

Nonsense

A nonsense mutation produces a premature STOP codon

Question 3

Missense

Answer 3

substitution that results in a different amino acid is
called a
missense mutation

Question 4

Frameshift Mutations

Answer 4

– shifts the reading frame of the codons so that a completely different amino acid sequence is produced from the point of the shift. Will likely not produce a functional protein

Question 5

Point Mutations – change in one nucleotide

Answer 5

Point Mutations – change in one nucleotide
○ Substitution
○ Substitutions will only affect a single codon
○Insertion (Frameshift)
○Deletion (Frameshift)
