Scientists produce two polypeptides, X and Y. Both are the same length and contain exactly the same number and types of amino acids. However, the amino acids occur in a different sequence. Under identical conditions: - Polypeptide X shows 100% relative binding to a target molecule. - Polypeptide Y shows only 8% relative binding. Which statement best explains the difference? 💬 Choose your answer and add one sentence of biological reasoning. A letter by itself does not count!
