A gene from a fish was transferred into yeast cells. The protein made by the yeast had the same amino acid sequence as the protein made from this gene in fish cells. Which conclusion is supported by this result?
The yeast cells changed the base sequence of the fish gene to match their own genes.
Each single base in the fish gene codes for one amino acid in the yeast protein.
The order of amino acids in the protein determines the order of bases in the gene.
Fish cells and yeast cells use the same triplet of bases to code for each amino acid.
