Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to ...

The chromatids (now also considered chromosomes) arrive at the opposite ends of the cell, and new nuclear membranes form. Mitosis, which describes only the division of the nucleus, is now complete.

Right timing of cell division His group has now discovered that Plk1 is not essential for the start of cell division. "Rather, it acts as a molecular switch to ensure that cells start dividing at ...

The unexpected discovery may provide scientists with new insights into how cancer develops — and how to combat it.

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...

All cells are produced from other cells by the process of cell division. Cell division occurs when one cell divides to produce two new cells. Unicellular organisms use cell division to reproduce.

The stages outlined in the following example show a cell with a diploid chromosome number of four (two sets of two chromosomes) undergoing cell division ... and new nuclear membranes form around ...

in which the nuclear envelope – the two-layered membrane separating the nucleus from the rest of the cell – breaks down when ...

A renewed understanding of the protein's dual role introduces the possibility that its overexpression promotes cancer development by enhancing the expression of genes responsible for cell division.

The five phases of mitosis and cell division tightly coordinate the movements ... Prometaphase begins with the abrupt fragmentation of the nuclear envelope into many small vesicles that will ...

Mitosis describes the process by which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA. (Cytokinesis describes the division of the rest of the cell.) ...
