Adapters consist of a core sequence (black) and an enzyme-specific sequence (red). The enzyme-specific sequence allows the ligation of the adapters to the resulting restriction fragments (green) ...

Definition: A restriction enzyme is a DNA-cutting protein, found mainly in bacteria and archaea, that recognizes a specific short DNA sequence and cleaves the double helix at or near that site. By ...

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 ...

Key to Invitrogen's Gateway technology is the "entry clone," which contains a fragment of interest in a recombinase-ready plasmid. Researchers can quickly and efficiently move between expression ...

The first of these methods was Southern Blotting, developed in 1975 by Edward Southern, and is used to detect the sequence of DNA fragments. Since then, two other methods have been developed, called ...
