Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...

A metabolic enzyme also binds and unwinds RNA to promote translation of cell cycle genes. This dual role links energy status to cell division, revealing a molecular switch that controls growth, and ...

In early embryos, the first cell divisions must be extremely rapid and precisely controlled to ensure successful development. This balance is found to arise from a tight coupling between the clock ...

Adele L. Marston is in the Centre for Cell Biology, School of Biological Sciences, University of Edinburgh, Edinburgh EH9 3BF, UK. Centromeres vary widely in size and DNA sequence, ranging from ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive ...

Figure 1: A light micrograph of a large oocyte in an ovary. RIKEN researchers have found that MPS1 promotes timely spindle bipolarization when oocytes in mice undergo ...

A fertilized egg of an animal can be easily removed, and the process of cell division can be observed alive. However, a fertilized egg of a plant cannot be removed and observed alive since it lies ...
