A cell is at the M (spindle) checkpoint. Select all correct statements about what this checkpoint checks or helps prevent.

  1. A

    It checks that chromosomes are properly attached to spindle fibers.

  2. B

    It checks that cell growth signals are present before DNA replication.

  3. C

    It helps reduce the risk of daughter cells receiving unequal chromosome sets.

  4. D

    It ensures that DNA is copied again between meiosis I and meiosis II.
