medium · MCAT bio-biochem
A point mutation in a gene changes a codon from 5'-UAC-3' to 5'-UAA-3'.
What is the most likely structural consequence for the resulting polypeptide?
- The protein will be truncated due to a premature stop signal.
- A different amino acid will be incorporated, potentially altering folding.
- The reading frame will shift, scrambling all downstream residues.
- The protein sequence will remain identical due to the degeneracy of the code.
