Question

a codon is a set of three nucleotides that correspond to a specific amino acid. the table below shows various dna codons and their corresponding amino acids.
1
in the dna strand below, two nucleotides were reversed during replication.
what will happen when the replicated dna strand is translated into a protein?
a. the same amino acid, isoleucine, will be added
b. no amino acids will be added at all
c. nothing will happen.
d. tyrosine will be added instead of isoleucine

Explanation:

First, identify the codons in the original and incorrect DNA strands. The original strand 'ATGATT' contains the codons 'ATG' (methionine - start) and 'ATT' (isoleucine). The incorrect strand 'ATGTAT' has codons 'ATG' (methionine - start) and 'TAT' (tyrosine). So, when translated, tyrosine will be added instead of isoleucine.

Answer:

D. Tyrosine will be added instead of isoleucine
