Scientists at INRS have identified a family of enzymes, known as Ssn, that can make targeted cuts in single-stranded DNA—a feat never before achieved. This discovery not only fills a major gap in ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

To our immune system, a potentially lifesaving gene therapy can look a lot like a dangerous infection. That's because most genetic medicine uses viruses or double-stranded DNA to deliver genetic ...

Professor Dongsheng Liu of Tsinghua University, Professor Ziyang Hao of Capital Medical University, and Researcher Yuanchen Dong of the Institute of Chemistry, Chinese Academy of Sciences, have ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

An INRS team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA . A few years ago, the advent of technology known as CRISPR was a major breakthrough in the ...
