In PART 1, you replicated DNA but did not change any settings.  In PART 2, your GOAL is to investigate the effects of changing variables in the simulation on your DNA replication.  To complete this goal, you will need to complete a second set of CHALLENGES.

[NOTE:  If at any time in Challenges 5 through 7, you “run out of DNA” to replicate, just reset your simulation and continue with your challenge.]
