Question 10 (4 points) Although all protein structures are unique, there are common structural building blocks that are referred to as regular secondary structures, Some proteins have alpha-helices, some have beta-sheets, and still others have a combination of both. What makes it possible for proteins to have these common structural elements? 12 15 a) the hydrophobic-core interactions. b) hydrogen bonds that form along (alpha helices) or between (beta sheets) polypeptide backbones. c) side-chain interactions d) specific amino acid sequences. 7...
