Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, ...
Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a dangling single-strand end into intact ...
At dawn in this small Amazonian village in Brazil's Para state, flocks of noisy green parrots soar overhead as children run and play between wooden homes, kicking up sandy soil—in places white and bare as a beach.
In a study with implications for chronic infections, Princeton researchers have described multiple pathways that some bacteria use to tolerate normally lethal antibiotic treatments. The findings overturn common assumptions ...
Repeat sequences are ubiquitous in the genomes of prokaryotes and eukaryotes. The rearrangement between direct repeats can result in deletions or expansions of DNA sequences, contributing to the genetic plasticity, regulation ...
Researchers at Chalmers University of Technology, Sweden, have discovered a new aspect to the way that DNA binds itself, and the role played by hydrophobic effects. They show how small changes in water properties can delicately ...
Using a piece of molecular "Velcro" to attach a light-emitting probe to a protein molecule, University of Wollongong (UOW) researchers have unlocked the mystery of how an important protein goes about repairing damaged DNA ...
For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth ...
DNA is the stuff of life, but it is also the stuff of nanotechnology. Because molecules of DNA with complementary chemical structures recognize and bind to one another, strands of DNA can fit together like Lego blocks to ...
Researchers from UAB describe for the first time, in a work published in PLOS ONE, a model of the behaviour of a bacterial colony that shows how it protects itself against toxic substances like antibiotics during the colonisation ...
