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 ...

Japanese researchers report a new ion detector, MARIO. Using it, they show that changes in the intracellular concentration of free magnesium ions (Mg 2+) is critical for the chromosome folding that ...

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 ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 chromosomes ...
