Cell Division Cells can divide in three ways, binary fission, mitosis, and meiosis. Prokaryotes reproduce by binary fission in which the cell basically divides in half. The single, circular DNA, attached to the plasma membrane, duplicates, and the cell begins to grow. Continued growth of the cell separates the chromosomes, and eventually the plasma membrane and cell wall pinch in and create two new cells. Eukaryotes go through a cell division cycle, including interphase and the mitotic phase. Interphase is divided into four stages, G1, S, G2, and M. In G1, cell growth takes place. The organelles get larger and the cell prepares for mitosis. The reproduction of DNA and the replication of chromosomes occur in the S phase, and final preparations for cell division occur in the G2 phase. Actual cell division occurs in M phase (mitosis). Mitosis has four sub-phases, prophase, metaphase....
