These chromosomes, carrying genetic information, align in the equator of the cell between the spindle poles at the metaphase plate, before being separated into each of the two daughter nuclei. This alignment marks the beginning of metaphase. [2] Metaphase accounts for approximately 4% of the cell cycle's duration. [citation needed]

Not properly "a" map projection because it is on two surfaces instead of one, it consists of two hemispheric equidistant azimuthal projections back-to-back.

In animals the cytokinesis ends with formation of a contractile ring and thereafter a cleavage. But in plants it happen differently. At first a cell plate is formed and then a cell wall develops between the two daughter cells. [36] In Fission yeast the cytokinesis happens in G1 phase. [37]
Four phases of mitosis: prophase, metaphase, anaphase, and telophase: Prophase: Chromatin into chromosomes, the nuclear envelope breaks down, chromosomes attach to spindle fibers by their centromeres. Metaphase: Chromosomes line up along the metaphase plate (center of the cell). Anaphase: Sister chromatids are pulled to opposite poles of the cell.

Early world maps cover depictions of the world from the Iron Age to the Age of Discovery and the emergence of modern geography during the early modern period.Old maps provide information about places that were known in past times, as well as the philosophical and cultural basis of the map, which were often much different from modern cartography.
