Question

by dragging and dropping, sort the statements below into the correct column based on the type of protein structure they describe. primary structure secondary structure tertiary structure quaternary structure disulfide bonds between distant cysteines in a polypeptide chain are often involved. alpha helix and beta pleated sheets are examples. order and sequence of amino acids. unaffected by denaturing conditions. determined by hydrogen bonding of nearby amino acids. two or more polypeptide chains interacting.

Explanation:

Primary structure is the order and sequence of amino - acids and is unaffected by denaturing conditions. Secondary structure is determined by hydrogen bonding of nearby amino acids, with alpha helix and beta - pleated sheets as examples. Tertiary structure often involves disulfide bonds between distant cysteines in a polypeptide chain. Quaternary structure is when two or more polypeptide chains interact.

Answer:

Primary Structure: Order and sequence of amino acids, Unaffected by denaturing conditions
Secondary Structure: Alpha helix and beta pleated sheets are examples, Determined by hydrogen bonding of nearby amino acids
Tertiary Structure: Disulfide bonds between distant cysteines in a polypeptide chain are often involved
Quaternary Structure: Two or more polypeptide chains interacting
