An organism grows and repairs its body using a form of cell division known as mitosis. To divide, a cell must replicate the chromosomes, which carry the DNA (the instructions needed to build the body) ...
Caulobacter crescentus has emerged as a premier model for studying bacterial cell cycle regulation due to its distinctive asymmetric division, which produces two morphologically and functionally ...
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 ...
If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged. When it is time for cell division, and the ...
Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours -- sometimes more than a day -- in a ...
Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...
Temporarily disabling a protein complex that organizes DNA into loops inside the cell's nucleus drastically disrupted the ...
A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...
If scientists could shrink themselves to microscopic size and take a journey through the human body—like the submarine crew ...
