A new study challenges prevalent models of chromosome formation during mitotic cell division. The study compared the dimensions of chromosomes in yeasts and humans and found that not only is the width ...

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 ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the ...

It took roughly 100 years to fill in all the missing details of the Y chromosome. Despite its macho connotations, the Y chromosome is among the tiniest of the 46 chromosomes in the human genome. It ...

A new study by researchers at the University of Wisconsin–Madison provides the first empirical evidence connecting the chromosomal location of genes to natural selection, indicating the arrangement of ...

SEM images of male and female human aortic valve tissue samples from two healthy patients and two patients diagnosed with AVS. Scale bars, 5 micrometers. A study led by bioengineers at the University ...

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 ...

Depending on the setting, the ability of a crucial bacterium in biotechnology—Agrobacterium tumefaciens—to transfer its DNA to a host plant can make it either a pathogen that damages crops or a ...
