A cultured mouse cell line has a mutation in a gene encoding a ribosomal protein. The mutant protein impairs the fidelity of translation such that incorrect amino acids are incorporated at higher rates than normal during protein synthesis. It also slows the rate of mRNA translation and increases the duration of the cell cycle, i.e., the mutant cells grow and divide more slowly. Researchers noted that these cells express higher levels of chaperone proteins than normal cells. Which of the following is the most likely explanation for the elevated chaperone levels.
