1. An unfertilized egg cell contains half as many DNA molecules as a fertilized egg cell.
   
2. An unfertilized egg cell contains the same number of DNA molecules as a fertilized egg cell.
   
3. An unfertilized egg cell contains twice as many DNA molecules as a fertilized egg cell.
   
4. An unfertilized egg cell contains four times as many DNA molecules as a fertilized egg cell.
