Substitution
Frameshift
Silent
Missense
What type of mutation results when a base is deleted from the DNA sequence?
Substitution

A mutation changes one base in the DNA but the amino acid stays the same. This is called a:
Silent mutation
Frameshift mutation
Nonsense mutation
Insertion mutation
Which of the following best describes a missense mutation?
A base is added
A base is deleted
A base is substituted, causing a change in one amino acid
A base is substituted, causing a stop codon
What happens during a nonsense mutation?
A stop codon is introduced early
A protein is made longer than normal
A base is deleted but the protein stays the same
One amino acid changes to another

Frameshift mutation
Nonsense mutation
Missense mutation
Silent mutation
A substitution mutation changes a codon from UAU to UAA. What kind of mutation is this? Hint UAA is a stop codon
Silent

Nonsense
Insertion
Which mutation is most likely to lead to a nonfunctional protein?
Silent
Missense
