The alpha-helix and b-sheets are examples of the structure of a protein. the alpha-helix and b-sheets are examples of the structure of a protein. primary secondary tertiary quaternary pentanary.

The correct answer is - Secondary structure.

Explanation:

Proteins are made up of the long polypeptide chain made up of the amino acid sequences. Folds of the primary structure makes the secondary structure. It is a three-dimensional structure of the protein.

Two common tyoe of the secondary structure of proteins is beta-sheets and alpha-helices. Omega loops and beta turns, exist as well in this category of protein.

Thus, the correct answer is - secondary structure.

the answer is false?
