Final answer:
In normal or unstressed cells, chaperones assist in proper protein folding and prevent protein aggregation, ensuring proteins achieve their correct structure and function.
Step-by-step explanation:
Chaperones play a crucial role in the proper functioning of proteins within cells. In normal or unstressed cells, the primary function of chaperones is to assist in proper protein folding, ensuring that proteins achieve their correct three-dimensional structure which is essential for their functionality. Chaperones help prevent improper protein aggregation, which can lead to dysfunctions and diseases, and they also safeguard against potential errors that could occur during the folding process caused by changes in cellular conditions such as pH and temperature.
