Each cell needs to have DNA in it in order to function (with the one key exception of a red blood cell which has no nucleus). In order to make sure each copy of the cell that is produced during cell division has the necessary information to function,the DNA must first be replicated and then each of the cells gets one copy of the DNA.
DNA replication begins when the two sides of the DNA molecule unwind and seperate, like a zipper unzipping.
Cells, although they range in size and shape, cannot become too large, or they may become unable to support their own functions.
im not really sure
When a cell grows during interphase, the surface area and volume of the cell are very important. Once the cell reaches a certain size, it can't be satisfied. This meaning that the cell cannot receive nutrients and remove wastes fast enough. Once the surface area: volume ratio is too small, then the cell must divide in order to live.
It must make a copy of its deoxyribonucleic acid (DNA).
Cells must copy their DNA before they can divide into new cells. Replication (of DNA) before division (of the cell)
1. Interphase 2. Prophase 1 3. Metaphase 1 4. Anaphase 1 5. Telophase 1 and Cytokiesis 6. Prophase 2 7. Metaphase 2 8. Anaphase 2 9. Telophase 2 and Cytokiesis
Before a cell can separate, it has to unravel its chromosomes and clone all its DNA

before the parent cells divide they have to find there matching cell

If a cell divides into two cells, duruing telophase, then there must be one nuclear membrane per cell. Therefore the answer to your question should be 2.
23 because the chromatics must divide and finish mitosis
It ensures that each newcell will be an exactcopy of its parent cell.
Cells Must divide: for health (white blood cells will increase in #'s in response to a virus attack) for regeneration (replacement of aging cells) for growth (accumulation of cells) for repair for differentiation or specialization of cell type reproduction (single-celled) organisms efficiency of exchange of materials across cell membrane
