Web30 mrt. 2024 · Delineating quiescence and dormancy. Quiescence (noun) is a labile state of a cell, embryonic or meristematic structure, where division of the cell or cell population is repressed by non-cell-autonomous processes. Cell division may not have ceased or stalled, and evidence suggests that mitosis continues even in stem cell populations. WebOn the other hand, meiosis is two nuclear divisions that result in four nuclei, usually partitioned into four new cells. The nuclei resulting from meiosis are never genetically identical, and they contain one chromosome set only—this is half the number of the original cell, which was diploid ( Figure 7.6 ).
Web19 aug. 2024 · Mitosis and meiosis are nuclear division processes that occur during cell division. Mitosis involves the division of body cells, while meiosis involves the division of sex cells.
