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 ...

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 ...

To many working biologists, DNA-modifying enzymes are tools, not unlike a pair of molecule-sized scissors. To Dr. Barry Stoddard, a professor in the Basic Sciences division at Fred Hutch, these ...
