and M. In G1 the cell grows and divides organelles. In the S phase, the chromosomes are copied and become sister chromatids. In G2, the cell grows more, making organelles and proteins. In the M phase (mitotic phase) several key steps occur for the cell to divide and become two ident...
Cell division is arrested, however, and the cell goes through another nuclear and mastigont division, resulting in a cell with four karyomastigonts. The cell with four karyomastigonts then divides into two cells, each with a double karyomastigont. 2. The opposite switch (Figure 4C), ...
Mitosis and meiosis are both processes of cell division, but they differ in terms of the number of daughter cells that are...

7.a spindle-shaped structure, composed of microtubules, that forms near the cell nucleus during mitosis or meiosis and, as it divides, draws the chromosomes to opposite poles of the cell. 8.a short, turned or circular ornament, as in a baluster or stair rail. ...
In the M phase, mitosis, a process in which the sister chromatids separate and the nucleus divides, and cytokinesis, a process in which the cytoplasm divides, occur. Because a diploid cell contains two sets of chromosomes (two genomes, one from each parent), mitosis ensures that the DNA ...
EVERY time a cell divides, the chromosomes must be distributed accurately to the daughter cells. Errors in distribution arise if chromosomes are improperly... X Li,RB Nicklas - 《Nature》 被引量: 1125发表: 1995年 Mitotic forces control a cell-cycle checkpoint. Tests the possibility of the det...
