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 ...

Restriction enzymes slice DNA, dice it, and snip it just where you’d like. But wait, there’s more! One of these DNA-omatics not only cuts like a pair of scissors, it looks like one too, report ...

Homologous recombination is an ancient process that functions to conserve genetic integrity and create genetic diversity. It relies on the formation of Holliday junctions — four-stranded DNA ...
