How will this mutation most likely affect the protain?
(1 point)
The mutation will have no affart because both codons code for the same amino acid
The mutation will cause translation to stop sony, producing a snarter, likay nonfunctional protein
The mutation will only change one amino acid, but the protain will function normally
The mutation will cause the bosome to siup the codon, contnung translation without intamuption

Answer 1

The mutation changing the mRNA codon from GAA to UAA is significant because GAA codes for the amino acid glutamic acid, while UAA is a stop codon. This means that the resulting protein will likely be shorter than intended, as translation will terminate prematurely at this stop codon.

Therefore, the correct answer to how this mutation will likely affect the resulting protein is:

**The mutation will cause translation to stop early, producing a shorter, likely nonfunctional protein.**
