Question

what structural level of proteins is represented by the sequence of amino acids in an alpha helix?
o tertiary structure
o primary structure
o secondary structure
o quaternary structure

Explanation:

The primary structure of a protein is defined by the linear sequence of amino - acids. Secondary structures like alpha - helix and beta - sheets are formed due to hydrogen bonding between the backbone atoms of the amino - acids in the primary sequence.

Answer:

primary structure
