Web8 mei 2024 · Why do chromosomes condense before and after mitosis? Chromosomes condense before mitosis to allow them the ability to move smoothly, without becoming entangled and breaking. (So, they are conveniently packaged for cell division, in which the chromosomes must move to both poles of the cell.) WebMitosis: Metaphase. When the chromosomes maneuver to the center of the cell, metaphase begins (Fig. 5). The spindle fiber network connects the centromere of the replicated chromosome to the outer part of each cell. The chromosomes now resemble the line of scrimmage of a football team, poised and waiting for some cellular signal to …

WebMitosis actually occurs in four phases. The phases are called prophase, metaphase, anaphase, and telophase. They are shown in Figure below and described in greater detail in the following sections. Mitosis in the Eukaryotic Cell Cycle. Mitosis is the multi-phase process in which the nucleus of a eukaryotic cell divides. WebMeiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis.
