The cell cycle consists of several checkpoints at which the cycle can be stopped before restarting. Which of the following is not a function of these checkpoints?
Supplying energy for the replication of chromosomes into pairs of sister chromatids
Ensuring that conditions are favorable for DNA replication and cell division
Making sure chromosomes are correctly replicated before nuclear division is complete
Limiting the amount of daughter cells that might contain genetic abnormalities
Preventing the start of mitosis until all chromosomes are fully replicated
