f2, R17, and MS2, which are quite similar among themselves and differ considerably from Qβ, a member of the third group. These four phages have been studied intensively in the last few years (3–6). Their RNAs consist of about 3500 nucleotides (7,8) and comprise three cistrons (10–12). The capsid co

Über die Kunst, sich selbst zu heilen 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:

Deutschland-Kompetenz für Chinal state of the cell. (This subject is extensively reviewed in refs. 1–4.) Thus at high growth rates ribosomal RNA is accumulated rapidly, the synthesis of ribosomal RNA accounting for up to 40% of the instantaneous rate of RNA synthesis (5,6), although the cistrons coding for these RNA species compr

Studies in HeLa cells indicated that both synthesis and maturation of 45S rRNA are depressed in the absence of protein synt

https://doi.org/10.1007/978-3-322-92048-5ecause the larvae originating from a clutch of eggs develop synchronously, it is possible to obtain material in large enough quantities for biochemical experimentation, even from specialized tissues such as the salivary glands. This makes it possible to correlate biochemical and morphological events

This feature allows potentially for isolation of the molecular elements involved in specific protein synthesis, including specific polysomes, mRNA, and genes, and an an
