Apoptotic DNA degradation has been thought to be a cell-autonomous process. Recent evidence suggests that heterophagic recognition and engulfment of dying cells by non-apoptotic cells may be ...

Restriction enzymes are one of the most important tools in the recombinant DNA technology toolbox. But how were these enzymes discovered? And what makes them so useful? Aa Aa Aa When I come to the ...

For this reason, compared with all previously available methods, it is much easier to ‘program’ CRISPR-Cas9 at a particular cutting point on the DNA strand. Various types of endonucleases – enzymes ...

Now, for the first time in a laboratory, Professor Veyrier's team has identified a family of enzymes capable of cutting a specific sequence in single-stranded DNA: the family of Ssn endonucleases.

“In the early days, you couldn’t do much with DNA because it was a very large molecule,” Roberts recalled. “As soon as the Type II restriction enzymes were discovered—and HindII in particular—it was ...

Recently, Professor Frédéric Veyrier at the Institut national de la recherche scientifique (INRS) and his team developed a new genetic tool based on a family of specific enzymes called Ssn that allows ...

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, ...

During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

This research also highlights how different enzymes in semen contribute to unique DNA fragmentation patterns, offering a new way to study male reproductive health at the molecular level.
