WebThe cell's DNA is replicated. -The chromosomes form pairs and the pairs are separated and pulled to opposite sides as the cell divides. -A second cell division follows, without DNA replication. -Four haploid daughter cells result, each with 23 chromosomes, but no pairs. Place the steps of mitosis in order.
