The Order of Amino Acids is the ____ Structure of Proteins

Question

The order of amino acids is the ____ structure of proteins.  
A) primary
B) secondary
C) tertiary
D) quaternary
E) stereo

Accepted Answer

The primary structure of a protein refers to the linear sequence of amino acids that make up the chain. It is the most basic level of structure in a protein and determines how the protein will fold and interact with other molecules.

B) secondary, C) tertiary, and D) quaternary structures refer to higher levels of protein structure that involve interactions between amino acid side chains and the overall three-dimensional shape of the protein, as well as the interactions between multiple protein subunits, if applicable.

E) stereo is not a recognized level of protein structure.
