Cell division is an essential process in humans, animals and plants as dying or injured cells are replenished throughout life. Cells divide at least a billion times in the average person, usually ...

Chromosomes are tiny, filamentous structures in the cell nuclei of living beings. They contain genes with genetic information, for example, related to the development or control of diseases. Every ...

Molecular biologists at UT Southwestern Medical Center have identified a gene called NORAD that helps maintain the proper number of chromosomes in cells, and that when inactivated, causes the number ...

Researchers report surprising results of experiments intended to explore the consequences of having too many or too few chromosomes, a phenomenon that biologists call aneuploidy. They were surprised ...

Although much progress has been achieved in understanding the genetic basis of adaptation, the drivers of genome evolution remain obscure. For instance, extensive variation among reptilian genomes ...

Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...
