A mutation in the third base of a codon for the amino acid Proline (Pro) will always be a silent mutation. Which of the following pieces of information best supports this claim?

As long as the first two bases on the mRNA codon are both C, it will always code for proline; regardless of the 3rd base

Proline is always made from the same 3 bases

Proline is a stop codon, so it isn't actually an amino acid and therefore cannot be mutated

Proline has evolved to become resistant to harmful mutations

Genetic mutations can be...

beneficial, harmful, or neutral
