Detailed explanation-1: -Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.
Detailed explanation-2: -This means that the cell separates all the copied chromosomes into 2 full sets. One at each end of the cell that is splitting in two. The other material that makes up the cell also splits in two. The result is two identical daughter cells.
Detailed explanation-3: -This is because all of the cells in our bodies start from a single fertilized egg. That first cell divided over and over again until a new baby was made. In the end, we all are made up of trillions of cells with nearly identical genes*. Since we start out as one cell, all our cells have the same DNA.
