Final answer:
Option D, containing Ala-Val-Leu-Ile-Trp, represents a sequence of non-polar, hydrophobic amino acids that would likely be found in the interior of a protein molecule.
Step-by-step explanation:
The question involves determining which stretch of amino acid residues would most likely be found in the interior of protein molecules. In general, non-polar and hydrophobic amino acids are found in the interior because they are shielded from water inside the protein's structure, whereas polar and charged amino acids tend to be on the surface, where they can interact with the aqueous environment. In this case, the correct answer is D. Ala-Val-Leu-Ile-Trp, as these are all non-polar, hydrophobic amino acids that are likely to be located in the interior of protein molecules.
