Isolation of a Pre-viral Deoxyribonucleic Acid

Abstract

IN 1943, we found that hydroxylamine can induce viral polyhedrosis in silkworms1. Pursuing this finding, one of us has established a metabolic cycle producing virogens and mutagens2. It has further been demonstrated that the polyhedral pre-viral genome is located in the chromosome of the host cell3. We have now succeeded in isolating the pre-viral deoxyribonucleic acid from the larval nucleus and have confirmed that hydroxylamine is able to accelerate its separation from the other nucleic acid portion.
