I understand that the primary structure is the sequence of amino acids. And the secondary structure is made from the interactions of neighboring amino acids, making the polypeptide chain fold into the secondary structure( alpha helixes and beat pleated sheets) . which form the tertiary structure. I don't really understand exactly what this question is asking.

Hi, here's my understanding and how I teach my students.

Tertiary interactions occur between the R-groups. For example, an amino acid might have a sulfur ( cysteine comes to mind), and this amino acid interacts with another. Usually the amino acids are distantly located, they don't need to be neighbors.
