New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated-able to read not only the ...

Ever wanted to ride a rollercoaster through the inside of a bacterial cell? Now you can, at least in Minecraft. Researchers from the University of Illinois at Urbana-Champaign created CraftCells – ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...
