In the early 1950s, experiments by two teams of researchers, Salvador Luria working with Mary Human and Joe Bertani working with Jean Weigle, showed that some strains of bacteria were more resistant ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

Scientists are pioneering a new method of genetic engineering for basic and applied biological research and medicine. Their work has the potential to open new doors in genomic research by improving ...

The video above has some helpful tips for designing PCR primers for one purpose - cloning with restriction enzymes. PCR or Polymerase Chain Reaction, is a very common tool used in molecular biology to ...

Bacteria and the viruses that infect them are engaged in a molecular arms race as ancient as life itself. Evolution has equipped bacteria with an arsenal of immune enzymes, including CRISPR-Cas ...

WEST LAFAYETTE, Ind. – Researchers at Purdue University have attached magnetic "nanoparticles" to DNA and then cut these "DNA wires" into pieces, offering the promise of creating low-cost, ...

"We are able to show that caloric restriction slows down aging by preventing an enzyme, peroxiredoxin, from being inactivated. This enzyme is also extremely important in counteracting damage to our ...

BOSTON – A team led by investigators at Massachusetts General Hospital (MGH) has overcome a major constraint for cutting and editing DNA by CRISPR-Cas enzymes and other technologies. The recent ...

Modular cloning and expression of complex genetic assemblies are becoming widely popular. Recent applications based on site-specific and homologous recombination have substantially improved the ...

Research by Professor of Chemical and Biomolecular Engineering Huimin Zhao and graduate student Behnam Enghiad at the University of Illinois is pioneering a new method of genetic engineering for basic ...
