Accompanying CRISPR sequences, there are 4-10 CRISPR-associated genes (cas), which are highly conserved and encode the Cas proteins. Cas proteins conduct adaptive immunity in prokaryotes (bacteria ...

Dr David Mayo-Muñoz, co-first author CRISPR-Cas are immune systems bacteria have that protect them from getting infected by bacterial viruses – called phages. It works by taking pieces of phage ...

CRISPR-Cas are immune systems bacteria have that protect them from getting infected by bacterial viruses -- called phages. It works by taking pieces of phage DNA and adding it to the bacterium's ...

A newly discovered bacterial defense protein named Cat1 reveals an extraordinary method of viral neutralization. All living ...

Bacteria-attacking viruses, known as bacteriophages, use small RNAs to disarm the CRISPR-Cas immune systems of bacteria. This discovery has now been documented by researchers at the University of ...

CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA ...

Clustered regularly interspaced short palindromic repeats (CRISPRs) and CRISPR associated genes (cas) are widespread in the genome of many bacteria and are a defence mechanism against foreign ...

The bacteria then use that information to identify ... Lab (called a “transposase”) uses custom-made RNA along with CRISPR-Cas proteins to guide the transposon with the DNA payload to the ...

About half of known bacteria, as well as most of other microbes known as archaea, have CRISPR-Cas systems. Bizarrely, even some viruses have co-opted the CRISPR-Cas machinery, to fight back ...

CRISPR-Cas systems are bacterial adaptive immune systems that target and cut the nucleic acids (DNA/RNA) of invading genetic parasites like bacteriophages (phages); viruses that infect - and ...

They engineered bacteria-hunting viruses ... without the double-strand DNA breakage commonly associated with CRISPR-Cas targeting.” The final test was designed to simulate a more natural ...
