This process is called non-allelic homologous recombination (NAHR; also known as ectopic HR), and is discussed below. Change in copy number involves change in the structure of the chromosomes such ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

When Kostas Konstantinidis proved that many bacteria—like plants and animals—are organized into species, he upended a ...

New research reveals that bacteria form species and maintain cohesion through frequent DNA exchange within species. This ...

One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA. This process ...

Molecular Cell. 1999). Whereas nonhomologous repair of DSBs is intact in these cells, homology-directed repair is significantly impaired. Homologous integration of transfected DNA is also reduced.

They found that a process called "homologous recombination" plays a major role in keeping microbial species together.

"When DNA damaged by radiation therapy was repaired by a method called homologous recombination, cancer cells died during the process of reproducing—a process called cell division or mitosis.

However, new findings from Konstantinidis and his team suggest otherwise, positing that bacteria not only form species but also maintain cohesion within these species through mechanisms that closely ...
