• adapt
• genetic
• beneficial
• evolution

Match the mutation with the descirption

• inserts a stop codon randomly

• nonsense

• delete nucleotide resulting in frameshif

• missense

• results in amino acid substitution

• insertation

• has not effect on amino acids

• silent

• insert nucleotide resulting in frameshif

• deletion

Select the missense mutation.
