Answer:
same as the number of chromosomes present
Step-by-step explanation:
During metaphase of mitosis, the number of DNA molecules in a cell is the same as the number of chromosomes present. This is because each chromosome contains a single, long DNA molecule that has been duplicated during S-phase of the cell cycle. Therefore, if a diploid cell contains 20 chromosomes, it will have a total of 40 DNA molecules during metaphase of mitosis. This is because each chromosome will consist of two sister chromatids, each containing a copy of the original DNA molecule. During metaphase, the replicated chromosomes line up along the equator of the cell and are ready to be separated into two daughter cells during anaphase.
