Quick, low-stakes observations focused on student learning allow administrators to provide teachers with useful feedback on ...

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 ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Asymmetric cell division can be divided into four main steps: symmetry breaking, polarity establishment, determinant segregation and spindle positioning. As a result of these steps, a mother cell can ...

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours -- sometimes more than a day -- in a ...
