(Phys.org)—A new DNA sequencing technique has enabled researchers to map for the first time the influential chemical modifications known as methylation marks throughout the genome of a pathogenic bacterium. By comparing these patterns between related strains of the bacteria, they stumbled upon a way that viruses that infect bacteria (known as bacteriophages) can dramatically alter their host.
