Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific world. Developed from a derivative of the immune system of bacteria, CRISPR enables double strands ...

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 ...

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 ...

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 ...
