Metaphase chromosomes make the classical picture of chromosomes . For classical cytogenetic analyses, cells are grown in short term culture and arrested in metaphase using mitotic inhibitor . Further they are used for slide preparation and banding ( staining ) of chromosomes to be visualised under microscope to study structure and number of ...

English: A diagram of mitosis stages Interphase (G₂): In this substage, the cell prepares for nuclear division and a protein that makes microtubles for cell division is synthesized. Prophase: The longest stage of mitosis. In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell.
Mitosis is the process by which a eukaryotic cell separates. Date: 8 September 2008: Source: Made myself based on the information in wikipedia, and the images:, , , and the video: Author: LadyofHats: Permission (Reusing this file)
G 2 phase, Gap 2 phase, or Growth 2 phase, is the third subphase of interphase in the cell cycle directly preceding mitosis. It follows the successful completion of S phase, during which the cell’s DNA is replicated. G 2 phase ends with the onset of prophase, the first phase of mitosis in which the cell’s chromatin condenses into chromosomes.
Micrograph showing condensed chromosomes in blue, kinetochores in pink, and microtubules in green during metaphase of mitosis. In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells.
Mitosis consists of two independent processes: the intra-chromosomal and the extra-chromosomal (formation of spindle) changes both of these being in total coordination of each other. This cell as seen under immunofluorescence contains four centrosomes, two at each end, with their own spindle fibers attaching to chromosomes at the metaphase plate.
