Item RH052001: There are half as many DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
How many DNA molecules are in an unfertilized egg cell compared to a fertilized egg cell? (A fertilized egg cell is an egg cell that has combined with a sperm cell.)
- There are half as many DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
- There are the same number of DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
- There are twice as many DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
- There are four times as many DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
