Abstract
Incorporation studies with 13C-, 15N-, and 2H-labeled substrates, followed by NMR analysis, show that the pyrimidine unit of thiamin (Vitamin B1) originates from a C5N fragment, derived from C-2',2,N,C-6,5,5' of pyridoxol (Vitamin B6) and an N-C-N fragment derived from L-histidine. Urocanic acid serves as an intermediate on the route of the N-C-N fragment of histidine into the thiamin pyrimidine.

Abstract
In addition to the RI (replicative intermediate RNA) and native RF (replicative form RNA), mouse hepatitis virus-infected cells contained six species of RNA intermediates active in transcribing subgenomic mRNA. We have named these transcriptive intermediates (TIs) and native transcriptive forms (TFs) because they are not replicating genome-sized RNA. Based on solubility in high salt solutions, approximately 70% of the replicating and transcribing structures that accumulated in infected cells by 5-6 h post-infection were multi-stranded intermediates, the RI/TIs. The other 30% were in double-stranded structures, the native RF/TFs. These replicating and transcribing structures were separated by velocity sedimentation on sucrose gradients or by gel filtration chromatography on Sepharose 2B and Sephacryl S-1000, and migrated on agarose gels during electrophoresis, according to their size. Digestion with RNase T1 at 1-10 units/microgram RNA resolved RI/TIs into RF/TF cores and left native RF/TFs intact, whereas RNase A at concentrations of 0.02 microgram/microgram RNA or higher degraded both native RF/TFs and RI/TIs. Viral RI/TIs and native RF/TFs bound to magnetic beads containing oligo(dT)(25), suggesting that the poly(A) sequence on the 3' end of the positive strands was longer than any poly(U) on the negative strands. Kinetics of incorporation of [(3)H]uridine showed that both the RI and TIs were transcriptionally active and the labelling of RI/TIs was not the dead-end product of aberrant negative-strand synthesis. Failure originally to find TIs and TF cores was probably due to overdigestion with RNase A.

Abstract
Under certain culture conditions, Miracil (35 mug/ml) halts the growth of uninfected Escherichia coli. Cellular ribonucleic acid (RNA) synthesis is almost completely suppressed, whereas deoxyribonucleic acid and protein synthesis are inhibited to a lesser extent. When the drug is added to host bacteria prior to infection with bacteriophage MS2, the phage adsorb to the cells, but penetration of the viral RNA is inhibited. Penetration may be achieved without further viral development by infection in the presence of chloramphenicol. If the bacteria are infected with MS2 in the presence of chloramphenicol, subsequently washed to remove the chloramphenicol, and then treated with Miracil at any time between 0 and 20 min postinfection, a second viral function is inhibited and the yield of progeny phage is reduced. Addition of the drug after 20 min postinfection does not inhibit the infection process. When Miracil is present from early times in infection, only a limited synthesis of both double- and single-stranded virus-specific RNA is observed. The viral RNA species thus produced do not appear to differ from those made in the absence of the drug. A comparison of the activities of the viral RNA synthetase produced during the course of infection in the presence and in the absence of Miracil suggests that a possible cause of the inhibition is the synthesis of an unstable enzyme in the presence of the drug.

Abstract
Synthesis of viral ribonucleic acid (RNA) polymerase, maturation protein, and coat protein in Escherichia coli infected with bacteriophage R17 occurs mainly on polysomes containing four or more ribosomes. The 30S ribosomal subunits through trimer-size polysomes, which are associated with all of the R17-specific proteins and are predominant in the infected cell, synthesize only coat protein. These structures may accumulate as products derived from larger polysomes as a result of failure in the release of nascent polypeptides after termination of chain growth. Appreciable amounts of viral coat protein remain attached to ribosomes and polysomes during R17 bacteriophage replication, supporting the hypothesis of the repressor role of this protein. The time course of synthesis of virus-specific proteins obtained from the polysomes of infected cells demonstrated regulated R17 messenger RNA translation consistent with the idea that coat protein is preferentially synthesized whereas the synthesis of noncoat proteins is suppressed.

Abstract
Ribonucleic acid (RNA) has been isolated from partially purified rubella virus preparations and fractionated by rate zonal centrifugation in sucrose density gradients. The bulk of the RNA sedimented as a sharp band with a sedimentation coefficient of 38S. Rubella virus RNA appears to be single-stranded on the basis of its sensitivity to the degrading action of ribonuclease. Fractionation by precipitation with 1 m NaCl, followed by chromatography on cellulose columns, and by rate zonal centrifugation in sucrose density gradients of labeled RNA isolated from actinomycin D-treated and infected baby hamster kidney cells revealed the presence of the following virus-specific types of RNA: (i) single-stranded RNA with a heterogeneous sedimentation pattern, the 38S viral RNA becoming the predominant species only after long periods of labeling late after infection; (ii) double-stranded RNA with a sedimentation coefficient of 20S; (iii) RNA apparently composed of 20S double-stranded RNA and single-stranded branches. On the basis of their properties, the last two species were tentatively identified as the replicative form and the replicative intermediate of rubella virus RNA. Rubella virus RNA was infectious.

Abstract
Poliovirus ribonucleic acid (RNA) polymerase crude extracts could be stored frozen in liquid nitrogen without loss of activity or specificity. The major in vitro product of these extracts was viral single-stranded RNA. However, after short periods of incubation with radioactive nucleoside triphosphates, most of the incorporated label was found in replicative intermediate. When excess unlabeled nucleoside triphosphate was added, the label was displaced from the replicative intermediate and accumulated as viral RNA. It is concluded from this experiment that the replicative intermediate is the precursor to viral RNA. In addition, some of the label was chased into double-stranded RNA. The implications of this finding are discussed.

Abstract
One hour after infection of chick fibroblasts with Semliki Forest virus (SFV), a viral ribonucleic acid (RNA) structure is present which has many of the properties described for the replicative intermediate of several RNA bacteriophages. These properties include a polydisperse nature on sucrose density gradient analysis, ribonuclease resistance, a variation in sedimentation pattern associated with changes in salt concentration, and recovery of infectious viral RNA upon denaturation. Most of the replicative intermediate present in SFV infection appears to be membrane-associated.

Abstract
Virus-specific ribonucleic acid (RNA), synthesized in influenza virus-infected cells from 3.5 to 7.5 hr after infection, was studied. After velocity centrifugation in sucrose, three peaks of virus-specific RNA could be identified: 34S, 18S, and 11S. These RNA species are predominantly single-stranded and consist of 90% viral (plus) and 10% complementary (minus) RNA strands. Most (75%) of the complementary RNA is single-stranded, i.e., not part of RNA duplexes or replicative intermediates. The 34S RNA species is an aggregate of 18S and 14S RNA species. Both 18S and 11S RNA species are relatively heterogenous compared to 18S ribosomal RNA, and these species probably contain different RNA molecules having closely related sedimentation coefficients.

Abstract
Infectious entities, extractable, with phosphate buffer, from tissue infected with potato spindle tuber virus and inciting symptoms on tomato that are typical of this virus, have properties incompatible with those of conventional virus particles. The infectious particles sediment in sucrose density gradients at approximately the same rate as particles with a sedimentation coefficient of 10S, are insensitive to treatment with organic solvents, and can be concentrated by ethanol precipitation. Treatment with phenol changes neither their infectivity nor their sedimentation properties. Infectivity is insensitive to deoxyribonuclease, but at low ionic strength it is sensitive to ribonuclease. At high ionic strength, infectivity partially survives incubation with ribonuclease. These properties, as well as elution patterns from columns of methylated serum albumin, suggest that the extractable infectious agent may be a double-stranded RNA.
