In 1965, Werner Arber’s seminal paper established the theoretical framework of the restriction-modification system, functioning as bacterial defense against invading bacteriophage (3). The basic premise is shown in the diagram to the right and is as follows: 1. Sticky ends and blunt ends. Donate or volunteer today! DNA cloning and recombinant DNA.
