    Notes: [Auszug] Cytoplasmic Nucleic Acids ACCORDING to the scheme initially proposed by /\ Gierer1 and Noll et al.2, messenger RNAs leave the cell nucleus to become individually associated with one or more ribosomes in the cytoplasm. Thereafter, the ribosomes assemble a specific protein by moving along the strand ...

    Notes: [Auszug] Fœtal synthesis. Dutch rabbits were opened under anaesthesia at the end of 24 days of gestation and each foetus was given an intraperitoneal injection of 50 pic. of lysine labelled with carbon- 14 (specific activity : 1 mc./mmole) through the uterine wall. At various intervals after ...

    Notes: [Auszug] INDISPENSABILITY of the nucleus for the prolonged continuation of normal cell metabolism has been recognized for many years. Yet, the precise nature of the exchanges which must at some time in the life of the cell occur between nucleus and cytoplasm remains to be fully elucidated. Pulse tracer ...

    Notes: Summary Observations on annulate lamellae and chromatoid bodies in spermatogonia of the cyprinid fish Pimephales notatus have revealed several commonly occurring features heretofore unreported: These include (a) the presence of annulate lamellae in close association with chromatoid bodies; (b) the existence of a chromatoid “band” or “shell” between the nuclear envelope and some chromatoid bodies with connections among them; (c) the presence of annulate pore complexes in the absence of well developed membrane envelopes as well as in association with such envelopes; (d) the presence of material just outside the nucleus and contiguous with nuclear pores which is of a similar density and texture to that of the chromatoid bands and chromatoid bodies; (e) filamentous material between the cytoplasmic sides of nuclear pores and the chromatoid “band”, bridging a distance of approximately 1000 Å and similar threads extending a like distance between chromatoid bodies (and bands) and annulate lamellae associated with them; and (f) mitochondria closely arranged about some chromatoid bodies.
