WebMetaphase is the second phase of mitosis. During metaphase, the mitotic spindle is fully formed and the chromosomes line up at the equatorial plane of the cell, which is the center of the cell. The chromosomes are attached to the mitotic spindle by their centromere, a region of DNA that connects the two sister chromatids, or copies of the ... WebMitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.

Web28 apr. 2024 · Mitosis is the step in the cell cycle that the newly duplicated DNA is separated, and two new cells are formed. This process is important in single-celled eukaryotes, as it is the process of asexual reproduction. In multi-celled eukaryotes, mitosis is how a single zygote can become an entire organism.
