The basic structure of most animal and plants cells is shown below. All cells are produced from other cells by the process of cell division. Cell division occurs when one cell divides to produce ...

During cell division, mitosis refers specifically to ... and they remain joined at a central point called the centromere. A large structure called the mitotic spindle also forms from long proteins ...

The five phases of mitosis and cell division tightly coordinate the movements ... their kinetochores (Figure 6), which are specialized structures in the most constricted regions of the chromosomes.

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order.

This video of a so-called HeLa cell dividing demonstrates how sensitive the cell division process is. While all is going well at the beginning of the video, as the clip nears its end you can see the ...

This structure, announced in their famous paper in the April 1953 issue of Nature, explained how the DNA molecule could replicate itself during cell division, enabling organisms to reproduce ...

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller ...

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller features, and electron microscopy resolves small structures, but samples ...
