Question

If you have a frame shift mutation past the first amino acid.

A) Only one amino acid affected
B) All amino acids affected
C) Only the first amino acid affected
D) No amino acids affected

Answer 1

The correct answer to the question about the effect of a frame shift mutation past the first amino acid is B) All amino acids affected. Frame shift mutations change the reading frame, causing extensive alteration to the sequence of amino acids and usually resulting in non-functional proteins.

Step-by-step explanation:

If you have a frame shift mutation past the first amino acid, the correct answer would be B) All amino acids affected. Frame shift mutations, such as the insertion or deletion of a nucleotide, cause a shift in the reading frame of codons during translation. Unlike a substitution mutation that might affect only one amino acid, frame shift mutations have a cascading effect, altering all subsequent amino acids in the protein beyond the point of the mutation. Consequently, these can often result in non-functional proteins due to the radical changes in their amino acid sequence.
