Myosin is a contractile protein found in muscles that is composed of three pairs of subunits, two heavy chains, and two pairs of two different types of light chains, for a total of six subunits. Myosin contains what level(s) of protein structure?

primary, secondary, tertiary, and quaternary structure

Explanation:

Myosin is a contractile protein found in muscles that is composed of three pairs of subunits, two heavy chains, and two pairs of two different types of light and it contains three levels of protein structure which areprimary, secondary, tertiary, and quaternary structure

Primary structure refers to the sequence of residues that made up the protein (Myosin).The primary structure are made up of only the covalent bonds linking those residues together.

Secondary Structure refers to the structural level that describes the local folding pattern of the backbone of the polypeptide bond, and this polypeptide is stabilized by the presence hydrogen bonds that exist between N-H and C=O groups.

Tertiary Structure refers to the level of structure that give details of how the regions of secondary structure is folding together and also how the polypeptide chain is arranged in 3D, and also the helices,and other loops and folds.
