prompts
1 protein structure achieved when alpha-helical or beta-pleated regions of the polypeptide chain fold upon one another to produce a compact ball-like, or globular, molecule.
2 the sequence of amino acids that form the polypeptide chain.
3 protein structure represented by alpha-helices and beta-sheets.
4 two or more polypeptide chains, each with its own tertiary structure.

Explanation:

1. Matching for Prompt 1

The description in prompt 1 is about the folding of alpha - helical or beta - pleated regions (which are secondary structure elements) to form a globular molecule. This is the definition of tertiary structure.

The sequence of amino acids in a polypeptide chain is the definition of the primary structure of a protein.

Alpha - helices and beta - sheets are the main elements of the secondary structure of a protein.

Answer:

Tertiary
