A certain species has a diploid number of 12. How many DNA molecules will be found in a cell of this species when it is in prophase of mitosis? 24 O 12 48

Solution

Answer is 24.

In the prophase the sister chromatids do not separate. Each chromatid represents a single molecule of DNA. So there would be 12 chromosomes and 24 chromatids or DNA molecules.
