A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At ...

Centromeres are regions of DNA where the cell's machinery grabs each chromosome and pulls it into the two daughter cells. Centromeres are essential for accurate chromosome segregation in every ...

Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...

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 ...

Just one enzyme manages the refilling of the cellular soda machine that replicates our genes. PLK-1 initiates a process in two protein groups, leading to creation of new CENP-A proteins. These CENP-A ...

A centromere is a specialized location in the DNA that functions as the control center of cell division and is maintained, unchanged, across generations of cells. It is characterized by a special ...

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 ...
