pls answer 6 and 7 6. Secondary structure (turn): The image below is of a polypeptide in secondary (20) structure level of protein folding. Specifically it is of a turn. Turns vary in length. The shorter the turn the more drastic the angle changes. The longer the turn, the more gradual the angles needed. a. Name the specific bond/interaction indicated by the dotted lines. b. Is this bond/interaction covalent or non-covalent? Is this bond/interaction permanent or transient? d. What parts...
