Recall the Bartel lab group experiment to create a ribozyme from scratch. If they had created exact copies of each ribozyme (rather than creating copies with a few differences), the ribozymes would have ________.
A) become more efficient with each round of selection
B) stayed the same with each round of selection
C) become less efficient with each round of selection
