A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). A typical ...
Human cells are extremely small and tightly packed – at about 20 micrometers across, ...
Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...
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 ...
This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...
Researchers have optimized a special X-ray process -- known as soft X-ray tomography -- to deliver high-resolution three-dimensional images of entire cells and their molecular structure in just a few ...
Scientists have crossed a startling new frontier in bioengineering: they can now fabricate intricate three-dimensional objects inside living cells. Instead of sculpting tissue from the outside, they ...
