hard · MCAT
A researcher discovers a mutation in a bacterial gene where a single cytosine is inserted into the middle of the coding sequence.
What is the most likely consequence for the resulting protein?
- The protein will be exactly the same due to the degeneracy of the genetic code.
- The mutation will be spliced out during RNA processing.
- A frameshift mutation will occur, likely resulting in a premature stop codon and a nonfunctional protein.
- A single amino acid will be substituted, but the rest of the protein will be normal.
