complete cell with 46 chromosomes. This cell is the start of a new human being.
             For a few hours after meeting, the two nuclei, one from the sperm cell and one from egg cell, lie next to each other in the center of the egg cell.
             The tail drops off from the sperm cell so that the two nuclei look alike. After this brief rest, a rush of activity begins. The two nuclei move together and the chromosomes pair up to make 46 needed to be a complete human tissue cell. But it's no ordinary cell. Almost immediately this new cell splits into two identical cells. They are smaller and still fit in the same membrane; like the original cell, each has 46 chromosomes.
             Cells divide by a process called mitosis. All cells plant, animal, and human go through approximately this same procedure to reproduce. The chromosomes make copies of themselves and then gather in the center of the cell. In human tissue cells this would
             mean that 92 chromosomes are crowded into the egg seems to disappear, and the double chromosomes start to pull apart. The dividing cell looks like a football
