Abstract: | Duck- and rabbit globin messenger ribonucleoprotein complexes isolated by oligo(dT) cellulose chromatography reveal an identical protein pattern—two main proteins of molecular weights of 73000 and 49000 daltons and minor components—whether the complexes have been liberated from polyribosomes with the EDTA-or the puromycin-high-salt method. In the globin messenger ribonucleoprotein particles of both species predominantly the protein with a molecular weight of 73000 daltons is attached to poly(A)-containing regions of the messenger RNAs. |
