Question

classify the following images according to the levels of protein structure each one represents. labels ① drop zones ← reset all primary structure (1/4) secondary structure (2/4) tertiary structure (3/4) quaternary structure (4/4)

Explanation:

The primary structure of a protein is the linear sequence of amino - acids. The secondary structure consists of local folding patterns like alpha - helices and beta - sheets. The tertiary structure is the three - dimensional structure of a single polypeptide chain. The quaternary structure is the structure formed by the association of multiple polypeptide chains. The first image with a linear chain of beads represents the primary structure. The fourth image with simple folded shapes likely represents secondary structure elements. The third image with a single, complexly folded chain is the tertiary structure. The second image with multiple chains associated together is the quaternary structure.

Answer:

First image: Primary Structure
Second image: Quaternary Structure
Third image: Tertiary Structure
Fourth image: Secondary Structure
