w All four statements in the table below might describe the same type of secondary structure in a protein. If they do, check the no errors box under the table, and then write the name of the secondary structure all four statements describe. But one of the statements might be inconsistent. That is, three of the statements might correctly describe a certain type of structure, and the fourth might say something wrong about that structure. If this is what you find, check the error box next to the statement that doesn't fit. statement error? x 5 Unlike elements of protein primary structure, it's stable at high temperatures and low pH because of the strong covalent forces holding it together. Within it, the protein backbone has the shape of a spiral staircase. Oo Overall, it has the shape of a cylinder. Oo The hydrogen bonds that hold it together go between NH and C=O groups on the backbone of the protein chain and separated by four a carbons. No errors. Name of secondary structure described: {]
