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 ...

Scientists first observed the biological phenomenon of restriction and modification in the 1950s, but they did not identify and isolate restriction enzymes until the late 1960s. 3 In 1970, Hamilton ...

A Nobel laureate, he identified an enzyme that cuts DNA, laying the groundwork for milestones in scientific research and ...

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 ...

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 ...
