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 ...

A new long-read sequencing technique has helped researchers investigate how DNA mutations arise in a variety of contexts. A collaboration of researchers led by NYU Langone Health and NYU Grossman ...

There’s an old saying about a dollar waiting on a dime. In other words, a monumental endeavor may become stuck at some point if a key preliminary element remains unavailable. The saying could be ...

Like the human immune system, bacteria learn from past infections. CRISPR sequences—short snippets of DNA from previous viruses—guide destructive enzymes towards invading bacteriophages that express ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...

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 ...
