True
Explanation:
During the late 1950s and early 1960s, Werner Arber and several others extended the work of an earlier Nobel laureate, Salvador Luria, who observed that bacteriophages (viruses that infect bacteria) not only induce hereditary mutations in their bacterial hosts but at the same time undergo hereditary mutations themselves. Werner Arber’s research was concentrated on the action of protective enzymes present in the bacteria, which modify the DNA of the infecting virus e.g., the restriction enzyme, so-called for its ability to restrict the growth of the bacteriophage by cutting the molecule of its DNA to pieces.
