Question

suppose that the triplet of nucleotides indicated in bold (agc) spans two codons, that is: cta and gcc. if the triplet agc were deleted from this dna coding sequence, what effect would it have on the resulting protein? 5-atgctagcctatcgtaac-3 all of the amino acids up to the deletion would be altered due to the frameshift. the two flanking codons would be altered, but the rest of the amino acid sequence would be the same because there would be no frameshift. the entire amino acid sequence would be altered due to the frameshift. all of the amino acids after the deletion would be altered due to the frameshift.

Explanation:

Frameshift mutations occur when nucleotides are inserted or deleted, altering the reading frame. Since the deletion affects two codons (AGC spans CTA and GCC), it disrupts the triplet reading frame. This means all subsequent codons (and thus amino acids) after the deletion will be misread. For example, if the original sequence was read as triplets like [codon1][codon2][codon3]... and a deletion in codon2 occurs, codon3 and beyond will be grouped differently (e.g., [newcodon2][newcodon3]...). So, all amino - acids after the deletion are affected due to the frameshift.

Answer:

All of the amino acids after the deletion would be altered due to the frameshift.
