Description
Fluorescent light micrograph of cells during mitosis (nuclear division). Mitosis is the formation of two daughter nuclei from one parent nucleus. Fluorescent markers have been used to highlight DNA (deoxyribonucleic acid, blue), alpha tubulin (red), a component of microtubules, and topoisomerase II (green), an enzyme that plays a role in the condensation of chromosomes prior to mitosis. The cell at left is in prometaphase with condensed chromosomes. The cell at centre is in metaphase, where the chromosomes align along the centre of the cell. The chromosomes start to move to the opposite poles, guided by microtubules, during anaphase (right).
