State the interphase stages shown by A and B in Fig. 3.2.
State the mitotic stage shown by D in Fig. 3.2.
Outline the changes that occur in a cell as it prepares for cytokinesis.
A stem cell from a female C. elegans contains 12 chromosomes. Complete Table 3.1 to show the number of nuclei in stages A, B and D of the cell cycle shown in Fig. 3.2, and the number of chromosomes in each nucleus during these stages.
State which mitotic stage is shown at D in Fig. 3.2.
Outline what happens in a cell as it prepares for cytokinesis.
A stem cell of a female C. elegans has 12 chromosomes. Complete Table 3.1 to show the number of nuclei in the stem cell during stages A, B and D of the cell cycle shown in Fig. 3.2, together with the number of chromosomes in each nucleus at these stages.
