Bildung der , aus den Staatskonzernen,substrate tRNAs (for a recent review, see ref. 4) could be related to the base sequence of the tRNA, to its overall geometry, or to both features. It is of interest, therefore, to study changes in the tRNA sequence and the effect of such changes in biosynthetic systems.

Host Proteins in the Replication of Bacteriophage RNA, An outstanding feature of this reaction is the actual replication of infectious bacteriophage RNA, as first shown by Spiegelman . (1). All of the reaction components have now been isolated as discrete species:

Although the figures are taken from our work, the main body of this article will include discussion of publications from various laboratories. For more general information, the reader may turn to one or the other of the numerous review articles on tRNA (e.g., refs. 1–5).
