Q: What structure is a larger assembly of several polypeptide chains that are now referred to as subunits of the protein?


Read this paragraph and choose the correct option from the provided answers:

Quaternary structure is a larger assembly of several polypeptide chains, now referred to as subunits of the protein. The quaternary structure is stabilized by the same interactions as the tertiary structure. Complexes of two or more polypeptides are called multimers. Specifically, a dimer contains two subunits, a trimer contains three subunits, and a tetramer contains four subunits.

 Choices:

- digital structure

- geological structure

- pyramid structure

- quaternary structure


A:
quaternary structure
