As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...
When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.
Accurate chromosome segregation and cell division are central to maintaining genomic integrity and ensuring proper development and tissue homeostasis. These processes rely on a complex network of ...
Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...
CAPTION: (Top) Condensins seem to act as a molecular crosslinkers to make loops. (Bottom, left) Condensins (red) locate around chromosome center. (Bottom, right) Nucleosomes around the periphery ...
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...
Studies show aging men often lose the Y chromosome in some cells, a change now linked to heart disease, cancer, and shorter lifespans.
The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Men lose their Y chromosomes as they age, here's why it matters
New research shows ageing men often lose the Y chromosome in some cells, a change linked to heart disease, cancer, ...
For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...
