A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

Cell division is the process of a single cell turning into two daughter cells – nearly identical copies of itself. To do this, the original cell needs to copy all its cellular components, including ...

An illustration of multicolored tangle of threads within a small black sphere. A 3D illustration shows DNA packaged into the nucleus, scientists with the 4D Nucleome project are now building accurate ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...

Cell division machinery, made up of microtubule filaments, attaching to centromeres to segregate identical copies of the cell's DNA during cell division. Alba Abad Fernandez. Scientists have solved a ...
