Question

Quizplus · Accepted Answer

The quaternary structure of a protein refers to the association between multiple subunits to form a functional unit. In the case of a ribosome, it is composed of a small and large subunit, with each subunit being made up of ribosomal proteins and ribosomal RNA molecules. Therefore, the entire structure of the ribosome with its associations between subunits is considered the quaternary structure.
