In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

A research group has developed a technology for mass-producing uniform artificial cells (lipid bilayer vesicles) with artificial model nuclei using microfluidic devices with high reproducibility. They ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

Scientists have uncovered a surprising twist in how cells behave when division goes wrong. Sometimes a cell successfully copies its DNA but fails to split into two, leaving it with double the genetic ...

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 ...
