(18) The "hexagonal ribbon" model proposes that hexagonal profiles are true cross-sections of elongated hexagonal ribbons.
(19) The results raise important questions as to the actual mechanism of transcription elongation, and suggest that it is a much more complex process than previously assumed.
(20) It has been possible to separate this dissipation from that associated with elongation factor Tu function.

(5) Both histochemical methods revealed the presence of intra-insular fiber plexuses.
(6) The present study was done in order to document the ability of the eighth cranial nerve of the bullfrog (Rana catesbeiana) to regenerate, the anatomic characteristics of the regenerated fibers, and the specificity of projections from individual endorgan branches of the nerve.
(7) "Acoustic" craters were produced by two laser pulses delivered into a saline-filled metal fiber cap, which was placed in a mechanically drilled crater.
(8) The minimal change in gel fiber size caused by slow A release implies that fibrin fiber size is primarily a function of ionic environment and not of the sequence of peptide release.
