title: RNA and DNA synthesis in developing eggs of the milkweed bug, Oncopeltus fasciatus (Dallas).
abstract: Ribosomal RNA synthesis in developing eggs of the milkweed bug, Oncopeltus fasciatus (Dallas), is turned on at gastrulation and is essentially turned off when organogenesis begins about 72 hours later. The pattern for DNA synthesis is similar although less pronounced.
