Mutations can be harmful, helpful, or neutral in their effect. A silent mutation tends to have a neutral effect as it does not result in coding for a different amino acid. Using your mRNA codon chart, give an other mRNA codon that this CUU could mutate to and still code for leucine.

CGA
CUA
CCA
CCU

A DNA sequence GCA ATG CAC is mutated and now reads CCA TGC AC. What type of mutation is this and what happens to the protein?

An insertion mutation, causing a frameshift, which leads to a longer protien
A nonsense mutation, causing a premature stop codon
A deletion mutation, causing a frameshift, which leads to a shorter protien
A silent mutation, causing no change to the protein
