Which of the following defines the primary structure of proteins?
A) the geometric arrangement of the backbone atoms
B) the geometric arrangement of the side chains
C) the sequence of the amino acids
D) all of the above

Question

Quizplus · Accepted Answer

The primary structure of a protein refers to the linear sequence of amino acids that make up the protein chain. This is what determines the overall three-dimensional structure and function of the protein. The geometric arrangement of the backbone atoms and side chains are important for determining the secondary and tertiary structure of the protein, but they are not the defining features of its primary structure.
