Under these conditions, monoribosomes (monosomes) migrated to the 15%-30% sucrose layer, while the heavier polyribosomes (polysomes) migrated to the 60% sucrose cushion.
The RER consisted of long lamellae containing a large number of ribosomes adhering to their lamellar walls and near of adjacent free ribosomes, forming polysomes. Intermediate filaments were observed close to the RER lamellae adjacent to vesicles of variable feature, shape and size (Figs.
Such groups of ribosomes are called polysomes and apparently allow the message to be used repeatedly before it is degraded.
The crystal structures of these minerals are based on regularly interstratified vaterite-like MC[O.sub.3] (M = Ca, Ba or [Na.sub.2]) and bastnasite-like REE(C[O.sub.3])(F,OH) layer modules (polysomes) (Donnay and Donnay, 1953; Ni et al., 1993; Yang et al., 1996; Grice and Chao, 1997).
