An evolutionary trait of humans and most animals is that they inherit mitochondrial DNA exclusively from the mother, even though the father's spermatozoa have mitochondria. If spermatozoa have ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study ...

Researchers from the University of Birmingham have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. The publication of two papers ...

New research shows hydroxyurea reshapes DNA replication in cancer cells, revealing stress responses that may help design ...
