A puzzling modification of DNA that is common in bacteria is not present in humans or other mammals. This has been shown in a new study by scientists at Linköping University in Sweden, published in Science Advances. The study shows that detection of the epigenetic mark 6mdA in animals was probably the result of limitations of the technology used and bacterial contamination of samples.
