If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and ...

Intracellular DNA can become damaged and/or distorted through a multitude of endogenous and exogenous sources (e.g., post-replication mismatches, base oxidation, cyclobutane pyrimidine dimers) 1,2.

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

Top: Chromosome separate with functioning SMC in two models, line drawing and filled-space. The red and pink dots indicate, respectively, ori on each copy of DNA. Bottom: DNA separating without ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

Red arrows indicate the DNA repair pathways that are known to aid bacterial survival as persisters and gamblers in the presence of fluoroquinolones. Blue color arrow indicates downregulation, while ...

High taxonomic diversity 1 and functional redundancy 2 are key features of the human gut microbiome and other complex microbial communities. These attributes are thought to underpin the resilience of ...

Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR). The insights, which expand our ...

A single protein bolted to the inner membrane of a bacterial cell can shred a virus’s DNA before that genetic material ever reaches the interior. That is the central finding behind SNIPE, a newly ...

Every cell in every organism on Earth copies DNA the same way. Except one bacterial protein — quietly doing something ...
