via mRNA," Molecular and Cellular Biology, vol.
The proportion of ribosomes active in polyribosomes
was measured in different developmental stages of the Antarctic sea urchin Sterechinus neumayeri.
Separation of the messenger RNA of reticulocyte polyribosomes
Laforin, defective in the progressive myoclonus epilepsy of Lafora type, is a dual-specificity phosphatase associated with polyribosomes
Most studies to date indicate that RNAi occurs in the cytoplasm by acting on translating polyribosomes
The cytoplasm also contained some mitochondria, granular endoplasmic reticulum, single ribosomes and polyribosomes
, and Golgi complexes (Figure 5).
FMRP associates with polyribosomes
as an mRNP, and the 1304N mutation of severe fragile X syndrome abolishes this association.
Transmission electron microscopy revealed disorganized endoplasmic reticulum, dispersion of the polyribosomes
, a variety of mitochondrial changes, and glycogen redistribution.
Export proteins are synthesized on polyribosomes
bound to the rough endoplasmic reticulum of the hepatocyte; in contrast, protein destined for intracellular use are synthesized on free rather than bound polyribosome
(Podolsky and Isselbacher, 1991).
Additional features of the tumor cells included moderately abundant mitochondria, stacks of rough endoplasmic reticulum, and polyribosomes
Mercury compounds can bind to the RNA of tobacco mosaic viruses (Katz & Santilli, 1962), several synthetic polyribosomes
, and yeast soluble RNA (Kawade, 1963).
As this technique is supposed to stain all the neurons because of the affinity of methylene blue by polyribosomes
and all the neurons, regardless of physiologic features, have this organelle, we would then have the total number of neurons.
