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 ...

When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

The improper segregation of chromosomes during cell division leads to abnormalities that disrupt the proper functioning of the cell. Cells with an abnormal number of chromosomes consequently activate ...

Researchers at Cardiff University have uncovered how a particularly severe form of DNA damage arises—shedding new light on mutation processes that contribute to cancer and inherited genetic conditions ...

A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery-how "selfish chromosomes" cheat the rules of genetic inheritance.

Researchers have discovered that a worm commonly used in the study of biology uses a set of proteins unlike those seen in other studied organisms to protect the ends of its DNA. University of Michigan ...

A new technique to clone and reassemble DNA, dubbed CReATiNG, could simplify and lower the cost to make synthetic chromosomes. Potential applications are numerous, including pharmaceutical production, ...
