A deeper look into the apparent self-defense mechanisms of these bacteriophage-resistant bacteria revealed their secret weapon: a group of enzymes called restriction endonucleases, or restriction ...

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 ...

Various types of endonucleases – enzymes that can cut DNA – were already known before CRISPR-Cas9. The discovery of restriction enzymes in the early 1970s heralded a new age in molecular biology.

The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like ...

Creative Enzymes, a recognized leader in providing high-quality biochemical solutions for life sciences research, is proud to announce the expansion of its product line to include a comprehensive ...

A restriction map of the 5.3 kb insert is prepared. The recombinant plasmid is digested with the enzymes listed above in single digests, and then several combinations of enzymes are tested in double ...

Feng Zhang, 2021 Richard Lounsbery Award recipient, will present the 2024 Lounsbery Lecture on "Exploration of Biological ...

The goal of my research is to understand the mechanisms and structures of enzymes that perform and regulate essential nucleic acid transactions. My research integrates diverse experimental approaches ...

We found that the glycerol levels in the body of these long-lived worms were lower than in shorter-lived worms that were not food restricted. Calorie restriction also heightened the activity of an ...

Research on two host strains of the fall armyworm (FAW), Spodoptera frugiperda [J. E. Smith], is reviewed. They differ at allozyme loci and mtDNA restriction enzyme profiles, in their development on a ...

We found that the glycerol levels in the body of these long-lived worms were lower than in shorter-lived worms that were not food restricted. Calorie restriction also heightened the activity of an ...

This useful study examines the function of the rnc gene, which encodes the RNase III ribonuclease, as it relates to virulence of Salmonella Enteritidis. The authors demonstrate that the rnc gene is ...
