Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

Researchers found that SMC proteins drive bacterial DNA separation by compacting chromosomes lengthwise, generating repulsive ...

Researchers at the University of Illinois Urbana-Champaign have built a computer simulation that tracks the entire life cycle ...

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

Cancer cells have special adaptation mechanisms that allow them to proliferate despite changes in their genetic makeup. Researchers at RPTU University Kaiserslautern-Landau, Southwest Germany, have ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...
