Cell division. Time-exposure light micrograph showing mitosis and cytokinesis (nuclear and cellular division,respectively). At top left the cells are in prophase,the chromosomes,made of deoxyribonucleic acid (DNA,white) are condensed. The third frame shows metaphase,with the chromosomes lining up along the centre of the cell. By the fifth frame the cell is in anaphase,the chromosomes are being pulled apart to opposite poles of the cell. The next frame shows telophase,during which the nuclear envelope reforms and the cell begins to divide into two. This process is completed during cytokinesis to form two daughter cells | |
