Answer: ATG AAG TTG GCT AA
Why: The original sequence (concatenated) is ATGAAGTTTGGCTAA (15 nt). Option 1 is ATGAAGTTGGCTAA (14 nt) — a one‑base deletion (not a multiple of 3) so the reading frame shifts. Compare codons:
- Original: ATG | AAG | TTT | GGC | TAA
- Mutant (option 1): ATG | AAG | TTG | GCT | AA( incomplete)
The downstream codons are altered, which is the hallmark of a frameshift deletion.
