Most animal cells undergo a shape change, known as mitotic cell rounding, to adopt a near spherical morphology at the start of mitosis. Most human cells are produced by mitotic cell division. Important exceptions include the gametes – sperm and egg cells – which are produced by meiosis. Meer weergeven In cell biology, mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes … Meer weergeven Overview The primary result of mitosis and cytokinesis is the transfer of a parent cell's genome into … Meer weergeven Forms of mitosis The mitosis process in the cells of eukaryotic organisms follows a similar pattern, but … Meer weergeven Cell rounding In animal tissue, most cells round up to a near-spherical shape during mitosis.
