A protein folds into a complex three-dimensional shape maintained by disulfide bridges, ionic bonds, and hydrophobic interactions. Which level of organization is this?
Q1. A protein folds into a complex three-dimensional shape maintained by disulfide bridges, ionic bonds, and hydrophobic interactions. Which level of organization is this?
Answer: Tertiary structure
Explanation: Tertiary structure is the final 3D shape maintained by disulfide bridges; secondary structure involves simple folding like alpha-helices via hydrogen bonds.
