Final answer:
The synthesis of long proteins does require a low error frequency in order to ensure the proper structure and function of proteins.
Step-by-step explanation:
The synthesis of long proteins does require a low error frequency. Errors during protein synthesis can lead to faulty proteins, which can have negative consequences for the cell and organism. For example, if the wrong amino acid is incorporated into a protein, it may not fold correctly or function properly. Low error frequency is essential for ensuring the proper structure and function of proteins.
