  abstract  = {Electron microscopic spread preparations of oocyte nucleoli (lampbrush stage) of various amphibians are quantitatively evaluated and the length distributions of repeat-, matrix-, and spacer-units along the rRNA cistron containing axes are given. The correlation of the matrix unit data with the gel electrophoretic pattern of labelled nuclear RNA from the same oocytes is examined. The mean value of the matrix unit corresponds fairly well to a 2.6 million D peak of pre-rRNA but the distribution of both matrix units and labelled pre-rRNAs shows an asymmetrical heterogeneity indicating the existence of some larger primary transcription products of rDNA. Novel structural aspects are described in the spacer regions which suggest that transcription does also take place in DNP regions between the matrix units. A special "prelude piece" coding for approx. 0.5 million D of RNA is frequently visualized in the spacer segments at the beginning of a matrix unit. Possible artifacts resulting from the preparation, the relative congruence between the data obtained using both methods, and the functional meaning of the findings are discussed against the background of current concepts of structural organization and transcription products of nucleolar DNA.},

  abstract  = {Cytochrome oxidase isolated from N eurospora crassa was resolved into seven protein eomponents by eleetrophoresis in polyaerylamide gels eontaining sodium dodeeylsulfate. The apparent molecular weights were determined tobe 41000, 28500, 21000, 16000, 14000, 11500 and 10000 for the eomponents 1, 2, 3, 4, 5, 6, and 7, respectively. The components 1, 2 and 3 are synthesized on mitochondrial ribosomes as shown by the incorporation of radioactive amino aeids in the presenee of cyeloheximide. Amino-acidanalysis of the isolated components 1, 2 and 3 revealed a high content of apolar amino acids and a low eontent of basic amino aeids compared to an average amino-aeid eomposition of components 4-7. Components 1, 2 and 3 eontribute 27.9°/0, 18°/0 and 14.2°/0 to the whole eytoehrome oxidase protein. This was calculated from the contributions of the single eomponents to the totalleueine eontent of the enzyme and the leueine eontents (nmol leueine per mg protein) of the single eomponents as determined by amino-aeid analysis. Equimolar relations of the components 1, 2 and 3 are found by dividing the amounts of protein by their apparent molecular weights. A stoichiometry of 1:1:1 results assuming a minimal molecular weight of 150000 for the whole cytochrome oxidase protein. On the basis of the heme a content a molecular weight of about 70000 per heme group was determined, using an absorption coeffieient L1e605 (redueed minus oxidized) of 12 mM-1 cm-1• It is concluded that the smallest structural unit of eytochrome oxidase contains two heme groups.},
