1. Compare DNA replication on the leading and lagging strands, including both similarities and differences. Which enzymes are involved?
2. Some bacteria may be able to respond to environmental stress by increasing the rate at which mutations occur during cell division. How might this be accomplished? Might there be an evolutionary advantage of this ability? Explain.
