Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Researchers at the University of Illinois Urbana-Champaign have built a computer simulation that tracks the entire life cycle of a living cell in four dimensions, capturing how the genetically minimal ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) interwoven through in the cell’s chromosome (red). Right side shows all the ...

Working with human breast and lung cells, Johns Hopkins Medicine scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many ...

(Nanowerk News) By simulating the life cycle of a minimal bacterial cell — from DNA replication to protein translation to metabolism and cell division — scientists have opened a new frontier of ...

When killer T cells of our immune system divide, they normally undergo asymmetric cell division (ACD): Each daughter cell inherits different cellular components, which drive the cells toward divergent ...

Arteriovenous malformations, a hallmark of hereditary hemorrhagic telangiectasia, may be driven by endothelial cell-cycle acceleration via CDK6, suggesting potential for repurposing CDK6 inhibitors.

Researchers discovered a kinase-driven phosphorylation switch that activates DNA packaging machinery, aligning nucleosomes at ...

A simulated cell in the early stages of division. Left half shows cytoplasm (blue cubes), mRNA degradation machinery molecules (pink), and sugar transporters (brown). Right half adds the membrane ...
