Step 1: Understand the problem
We are considering the effects of a single nucleotide deletion during DNA replication on the resulting protein. The nucleotide deletion will cause a frameshift, leading to changes in the amino acid sequence.
Step 2: Analyze the options
A) Obsess one amino acid of the protein to be incorrect: This is possible, as the deletion of a nucleotide will change the codon and might affect the corresponding amino acid. B) Obsess all of the amino acids of the protein to be incorrect: This is unlikely, as only the amino acids encoded after the deletion will be affected. C) Obsess the amino acids encoded by nucleotides after the deletion to be incorrect: This is correct. The deletion will cause a frameshift, changing the codons and thus the corresponding amino acids after the deletion point. D) Obsess the amino acids encoded by nucleotides before the deletion to be incorrect: This is incorrect, as the deletion only affects the codons after the deletion point. E) No effect on the resulting protein: This is incorrect, as a single nucleotide deletion will cause a frameshift and change the amino acid sequence.
Final Answer
The correct answer is C. A single nucleotide deletion during DNA replication will cause a frameshift, leading to changes in the amino acid sequence of the protein. Specifically, the amino acids encoded by nucleotides after the deletion will be incorrect.
