Cholera remains a major global public health challenge, with an estimated 1.3 to 4 million cases and tens of thousands of deaths reported worldwide each year. Caused by the bacterium Vibrio cholerae , ...

E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible. “It’s as ...

Researchers at Umeå University have identified a key molecular player that helps bacteria survive the hostile environment inside the body. Their study reveals how the protein RfaH acts as a protective ...

This image highlights two alternatives for the ribosome to be recruited to an mRNA that is still being synthesized by RNA polymerase (RNAP). RNAP (left, red) can directly deliver the mRNA to the entry ...

Researchers at the Indian Institute of Science (IISc), with collaborators from the Institute of Mathematical Sciences (IMSc), ...

Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...
