chromosomes duplicate before mitosis
The Chromosome go through 5 phases:

1. Interphase - the cell's chromosomes duplicate. the nucleolus is clearly visible ion the nucleus.

2. Prophase - the chromatid pairs are now visible and the spindle is beginning to form.

3. Metaphase - chromatid pairs are lined up in the center of the cell.

4. Anaphase - the chromsomes have seperated.

5. Telophase - in the final step, the cytoplasm is beginning to seperate.

The 2 new cells that were created, enter interphase and cell division usually begins again.
The chromosomes are duplicated before mitosis begins.
