Chromosome motor discovery supports DNA loop extrusion

It is one of the great mysteries in biology: How does a cell neatly distribute its replicated DNA between two daughter cells? For more than a century, we have known that DNA in the cell is comparable to a plate of spaghetti—a ...

How non-muscle cells find the strength to move

Researchers from the Mechanobiology Institute, Singapore (MBI) at the National University of Singapore have described, for the first time, the ordered arrangement of myosin-II filaments in actin cables of non-muscle cells. ...

Quantum dots illuminate transport within the cell

Biophysicists from Utrecht University have developed a strategy for using light-emitting nanocrystals as a marker in living cells. By recording the movements of these quantum dots, they can clarify the structure and dynamics ...

Viral protein transforms as it measures out DNA

To generate swarms of new viral particles, a virus hijacks a cell into producing masses of self-assembling cages that are then loaded with the genetic blueprint for the next infection. But the picture of how that DNA is loaded ...

Study shows how neurons reach their final destinations

As the human brain develops, neurons leave their birthplace and take a trip to distant locations. Once they reach their final destination, the neurons then send out axons and dendrites—the branches that receive and send ...

Researchers show that four-stranded DNA is formed and unfolded

Researchers at Umeå University in Sweden have discovered that specific DNA sequences that are rich in the DNA building block guanine in the yeast species, Schizosaccharomyces pombe, can form four-stranded DNA. In a study ...

Molecular motor grows cell's microtubules

Motor proteins that pause at the ends of microtubules and produce pushing forces can also stimulate their growth, according to researchers at Penn State. The proteins' function could be a critical component in understanding ...
