A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight ...

A computer simulation shows the two step process for a condensing chromosome, which happens as the cell moves from interphase to metaphase. In the first phase, chromatin loops of 80,000 to 120,000 DNA ...

(A) Histone staining images and OI-DIC density imaging of human living cells in the interphase (the phase between cell divisions, left) and mitotic phase (right). The bottom two rows are OI-DIC ...

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes. These histones carry numerous chemical modifications that act as molecular ...

Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism ...

There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...
