Final answer:
Molecular chaperones assist in protein repair by preventing aggregation during protein folding and ensuring proteins fold correctly.
Step-by-step explanation:
Molecular chaperones assist in protein repair by preventing proteins from aggregating during the folding process and ensuring they fold correctly. Even if a protein is properly specified by its corresponding mRNA, abnormal temperature or pH conditions can hinder proper folding. Chaperones bind to the target protein and help stabilize its structure, preventing aggregation and promoting correct folding. Once the protein is folded, the chaperones disassociate from it.
