Abstract

Young Oncopeltus eggs contain relatively large amounts of inosine which disappears during development. The guanosine content similarly decreases but less dramatically. Uric acid, on the other hand, stays relatively constant, a result in contrast to previously published reports. There is a rough correlation between the disappearance of the purine nucleosides and the synthesis of DNA and RNA during development. Thus the nucleosides probably act as stored precursors for the synthesis of one or other or both of these macromolecules.
