A researcher investigates a newly discovered virus and finds that its translation mechanism reads mRNA in an overlapping manner, where each codon overlaps by two nucleotides with the next (e.g., codon 1 consists of bases 1–3, codon 2 consists of bases 2–4, and codon 3 consists of bases 3–5).
If a single nucleotide substitution mutation occurs at position 3 of this mRNA sequence, what is the maximum number of amino acids in the resulting polypeptide that could be altered?
