Like people, bacteria get invaded by viruses. In bacteria, the viral invaders are called bacteriophages, derived from the ...

Bacteria steal DNA from silent viruses and use it like a memory bank. That memory helps them protect future generations.

CRISPR-Cas9 has two components. The first is an enzyme—Cas9—that functions as a cellular scalpel to cut DNA. (In nature, bacteria use it to sever and disarm the genetic code of invading viruses.) ...

Researchers have discovered a handful of new CRISPR-Cas systems that could add to the capabilities of the already transformational gene editing and DNA manipulation toolbox. Of the new recruits, one ...

Yet others, called base editors, change one letter of the DNA code to another. So why do we call it CRISPR? Cas proteins are used by bacteria to destroy viral DNA. They add bits of viral DNA to ...

Crucially, CRISPR systems can only destroy DNA that matches a "memory" captured from a prior infection and stored within the bacteria's own genome, say the researchers. In this way, the CRISPR ...

A breakthrough in safely delivering therapeutic DNA to cells using lipid nanoparticles could transform treatment for millions ...

Transposons, or "jumping genes"—DNA segments that can move from ... targeting transposons that coopted a CRISPR system—normally used by bacteria to defend against viruses—to target and ...

Bioengineering professor and The Grainger College of Engineering's Dean, Rashid Bashir, led a team of researchers in a ...

Woese Institute for Genomic Biology have developed a CRISPR-enriched metagenomics ... through the transfer of small pieces of bacterial DNA called antibiotic resistance genes.

They’re always collecting these mobile DNA pieces, and they’re making new functions ... subfamily of telomere-targeting transposons that coopted a CRISPR system – normally used by bacteria to defend ...
