Daphne identifies the entire sequence of nucleotides in a gene. Based on this information and the genetic code, she predicts the sequence of amino acids in the protein that the gene codes for. What is the MOST LIKELY reason that Daphne’s prediction would be incorrect?

The gene codes for a carbohydrate, and not a protein.
A mutation changes the genetic code that the cell uses.
The cell removes introns from pre-mRNA.
The cell removes introns from DNA.
