Question

Quizplus · Accepted Answer

Protein domains are distinct functional and/or structural units in a protein. They can fold independently into a stable structure, which allows them to retain their correct shape even when separated from the rest of the protein. This characteristic is crucial for their role in modular assembly and function of proteins.
