B) one strand of the original DNA ends up in each of the new DNA molecules.
C) the original DNA unwinds, and multiple copies of a region are transcribed before the DNA closes back up.
D) transcription factors determine where to begin DNA replication.
E) a cell that was diploid (2N) will now be tetraploid (4N) .
