Answer 1

I can’t reliably read the answer choices you pasted — they ran together. Could you repost them each on its own line (or label A, B, C, D)?

Meanwhile, here’s how to identify the correct choice and an example you can check against your options:

- A frameshift from a deletion means one (or any number not divisible by 3) nucleotides is missing. That changes every downstream codon.
- Count nucleotides: the original ATG AAG TTT GGC TAA is 15 bases. A single-base deletion produces a 14‑base sequence (not divisible by 3) and the codon groupings will all shift.

Example: delete the 4th base (the A in the second codon). New sequence:
ATGAGTTTGGCTAA
Group into codons: ATG AGT TTG GCT AA — note the codons after the deletion are different (frameshift) and the last codon is incomplete.

So when you repost the choices I’ll pick the one that (a) has one base missing (or another non‑multiple‑of‑3 change) and (b) shows shifted codons compared to the original.
