A biochemist studying a surface protein that is normally anchored to the cell membrane of a human cell determines the sequence of amino acids in the protein. Upon analyzing the amino acid sequence, the biochemist notices that most amino acids found in the protein sequence of the anchor portion of the protein are nonpolar uncharged amino acids. Which argument BEST explains this result?
