Question

Quizplus · Accepted Answer

Proteins are classified into families or superfamilies based on similarities in structure and/or function. This is because proteins with similar functions often have similar structural features that enable them to perform their specific roles. Physicochemical properties, evolutionary origin, subunit structure, and subcellular location may also be used to classify proteins, but they are not the primary criteria used for organizing proteins into families or superfamilies.
