There are four different categories of restriction enzymes. Type I restriction enzymes cut DNA at random locations far from their recognition sequence, type II cut within or close to their ...

“As soon as the Type II restriction enzymes were discovered—and HindII in particular—it was obvious that you could take a fairly large DNA and cut it into smaller pieces. And that offered you the ...

Researchers from the German Diabetes Center (DDZ) and the Heinrich Heine University Düsseldorf (HHU) have studied 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.

Today, scientists recognize three categories of restriction enzymes: type I, which recognize specific DNA sequences but make their cut at seemingly random sites that can be as far as 1,000 base ...
