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

In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in ...

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 ...

Structural biologists at the University of Wisconsin-Madison today published cryo-electron microscopy structures of the complete bacterial DNA replication restart complex — a molecular machine that ...

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 ...

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 ...

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist ...
