Mitosis. Image 1 of 8. Light micrograph of three hyacinth root cells during interphase, the stage between mitotic (nuclear) divisions. Mitosis is the formation of two daughter nuclei from one parent nucleus. During interphase the chromosomes, which are made of deoxyribonucleic acid (DNA, red), are contained within the cell nucleus (round). During interphase the cell grows, replicates organelles and replicates DNA so that each chromosome is made up of two identical chromatids, ready for mitosis. Magnification: x1150 when printed at 10 centimetres wide. For images showing the cell cycle see P672/146- P672/153.
