Detailed explanation-1: -Answer and Explanation: The answer is (c) Tertiary and quaternary. Interactions like hydrogen bonding among amino side chains stabilize the tertiary and quaternary structures of proteins.
Detailed explanation-2: -The primary structure is comprised of a linear chain of amino acids. The secondary structure contains regions of amino acid chains that are stabilized by hydrogen bonds from the polypeptide backbone. These hydrogen bonds create alpha-helix and beta-pleated sheets of the secondary structure.
Detailed explanation-3: -Primary structure, simply put, refers to the sequence of amino acids stringed together to form a protein. The structure is held together by peptide bonds between the carboxyl and amino group of each amino acid, which is formed during protein translation.
Detailed explanation-4: -The primary structure of a protein-its amino acid sequence-drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein’s unique three-dimensional shape.
Detailed explanation-5: -Hydrogen bonds provide most of the directional interactions that underpin protein folding, protein structure and molecular recognition. The core of most protein structures is composed of secondary structures such as helix and sheet.
