Detailed explanation-1: -The tertiary structure is the complete three-dimensional structure of a single biological unit.

Detailed explanation-2: -The structure of Biomolecule is the complex three-dimensional, folded configuration formed by a molecule of nucleic acid or protein which is vital for its functioning.

Detailed explanation-3: -As a result of all of these interactions, each type of protein has a particular three-dimensional structure, which is determined by the order of the amino acids in its chain.

Detailed explanation-4: -The correct answer is d. The hydrogen bonds, hydrophobic effects, salt bridge, and disulfide bonds are all possible interactions that may occur for the side chains (R-group) of the amino acids in the protein that will stabilize the tertiary structure.

Detailed explanation-5: -Primarily, the interactions among R groups creates the complex three-dimensional tertiary structure of a protein. The nature of the R groups found in the amino acids involved can counteract the formation of the hydrogen bonds described for standard secondary structures such as the alpha helix.
