Chromosomes in egg cells within fetal ovaries must be spliced and sorted perfectly. A new landmark study from UC Davis shows how protecting Holliday junctions allows this to happen.

Researchers have identified the exact DNA sequence where human chromosomes fuse to form Robertsonian chromosomes, a ...

The complete assembly of each human chromosome is essential for understanding human biology and evolution. Using complementary long-read sequencing technologies, we complete the first linear assembly ...

Women across the globe consistently outlive men by approximately five years on average, a phenomenon that has intrigued medical researchers for generations. Beyond simply living longer, women also ...

AMES, Iowa – A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, ...
