Mitosis is a cell division process in which genomic DNA replicates and separates into two new cells. Although it is essential in all eukaryotes, different species use different genes for mitosis. This ...

The process of mitosis has made more clear, thanks to recent research. A new study describes how Topo 2, an enzyme that disentangles DNA molecules and is essential for proper cell division. At this ...

Welcome to Mitosis vs. Meiosis. This half of the screen illustrates mitosis—the division of a cell's nucleus. Along with cytokinesis (the division of the rest of a cell), mitosis results in a parent ...

In this unit, you will learn what happens to DNA during both mitosis, the process of cell division that happens in most cells, and meiosis, the process of cell division that happens in cells that are ...

Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can ...

How do we grow from a single fertilized egg into a fully grown person with trillions of cells? Our cells divide, of course! And it's no mean feat. Each time a cell divides, it must duplicate our 23 ...

Chromosome segregation is restrained by the spindle assembly checkpoint (SAC) 8. The SAC monitors whether the kinetochores (protein assemblies that link the specialized areas of condensed chromosomes ...
