How head-on collisions of DNA protein machines stop replication

A new study describes how head-on collisions between protein machines on chromosomes can disrupt DNA replication and boost the rate of gene mutations that help bacteria survive hostile environments, resist antibiotics, and ...

Plants can 'switch off' virus DNA

A team of virologists and plant geneticists at Wageningen UR has demonstrated that when tomato plants contain Ty-1 resistance to the important Tomato yellow leaf curl virus (TYLCV), parts of the virus DNA (the genome) become ...

Enzyme corrects more than one million faults in DNA replication

Scientists from the Medical Research Council (MRC) Institute of Genetics and Molecular Medicine (IGMM) at the University of Edinburgh have discovered an enzyme that corrects the most common mistake in mammalian DNA.

Study offers new information for flu fight

Influenza virus can rapidly evolve from one form to another, complicating the effectiveness of vaccines and anti-viral drugs used to treat it. By first understanding the complex host cell pathways that the flu uses for replication, ...
