The cell cycle has been the subject of intense investigation during two periods since Virchow's 1855 realization that cells only arise from pre-existing cells. At the turn of the century ...

Scientists have identified a new variant of the cell cycle that could provide insight into how diseases like cancer occur. Maggie Chen is a scientist and science journalist covering health, biology, ...

Cell cycle transitions in eukaryotes are driven by cyclin-dependent kinases (for example, Cdk1 and Cdk2), which are regulated by the availability of their cyclin partners (for example, CycA and ...

Multicellular organisms need cells to divide so that organisms can grow and repair damaged tissue. Cells divide when: an organism grows an organism becomes damaged and needs to produce new cells ...

When looking at cells with a microscope, the length of different stages of the cell cycle can be estimated using the formula: \(\text{Length of time in phase}=\) \(\frac{\text{observed number of ...

A life cycle is the series of stages something passes through during its lifetime. We also use the term for things that are not living, like cell phones. The life cycle for anything you buy includes ...

A team led by Prof. Wuran Wei from West China Hospital of Sichuan University and Dr. Dechao Feng from the Division of Surgery ...

The cell cycle is understood to be the stages through which a cell progresses to ultimately divide into separate cells. It is this process that underlies the proliferation of life -; and is ...

New research offers unprecedented insight into how an enigmatic enzyme, known as CDK7, drives the cell cycle and cell proliferation.

New imaging reveals a built-in safeguard that allows B cell populations to rapidly expand in germinal centers without ...
