At which structural level of a protein would you find beta pleated sheets?

Question

Quizplus · Accepted Answer

At their secondary level, proteins can form alpha helices or beta pleated sheets.
The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain.
Protein tertiary structure is the three dimensional shape of a protein. The tertiary structure will have a single polypeptide chain "backbone" with one or more protein secondary structures.
The quaternary structure refers to the number and arrangement of the protein subunits with respect to one another.
