DNA and RNA synthesis in leaves during TYMV replication
… method for the isolation of TYMV-specific DS-RNA. 2. A procedure for the isolation of an outer chloroplast membrane fraction from healthy and diseased Chinese cabbage has been developed. This membrane system from diseased chloroplasts has been shown to contain most of the TYMV-specific DS-RNA. …

RNA synthesis in adult and senescent female Wistar rats
… tissues and cells to maintain homeostasis. RNA synthesis plays an important role in these functional capacities. Therefore, the objectives of this thesis were to determine any senescence-related changes in the process of RNA synthesis.

Decoding aberrant RNA Synthesis by the Influenza A Virus
… A viruses (IAV) are negative-strand segmented RNA viruses and are responsible for causing severe respiratory diseases and fatalities in humans. IAV encodes an RNA-dependent RNA polymerase (FluPolA), which is responsible for transcribing and replicating each segment of the viral genome. In …

Cytoplasmic RNA-dependent RNA-synthesis in maturing chicken erythrocytes.
An RNA-dependent RNA polymerase from ribosomes of maturing chicken erythrocytes was investigated. Concurrent with an increase in globin and RNA synthesis during phenylhydrazine induced anaemia, the total and specific activities of ribosome bound RNA-dependent RNA polymerase increased 40 and 9.4 …

Ice as a medium for RNA-catalysed RNA synthesis and evolution
… self-replication and evolution. According to the RNA World hypothesis, this could have been an RNA polymerase ribozyme capable of generating copies of itself from simple nucleotide precursors. In vitro evolution experiments have provided modern examples of such ribozymes, such as the R18 RNA …

Η ΕΠΙΔΡΑΣΗ ΤΟΥ ΣΥΜΠΛΟΚΟΥ ΔΕΞΑΜΕΘΑΖΟΝΗΣ-ΥΠΟΔΟΧΕΑ ΣΤΗΝ IN VITRO RNA ΣΥΝΘΕΣΗ ΑΠΟΜΟΝΩΜΕΝΩΝ ΠΥΡΗΝΩΝ ΘΥΜΟΥ ΚΑΙ ΣΥΚΩΤΙΟΥ ΑΡΟΥΡΑΙΟΥ
… SUCH BIOLOGICAL EFFECTS AS THE MODULATION OF THE RNA SYNTHESIS WHICH IS EXPRESSED AS INHIBITION IN THYMUS (FINAL RESULT IS DEATH) AND INCREASE IN LIVER. THE CELL DEATH OF THYMOCYTE POPULATIONS CAUSED BY DEXAMETHASONE WAS STUDIED IN IN VITRO SYSTEMS. WE ALSO STUDIED THE DIFFERENTIAL ACTION OF THE …

Επίδρση της Ν.Ν.- Διμεθυλο - Νιτρωδοαμίνη στο μεταβολισμό του RNA σε ΜΥΕΣ C57BL
… MALE C57B1 MICE CAUSES AN INHIBITION OF HN-RNA SYNTHESIS. THE EXTENT OF THE INHIBITION DEPENDS ON THE DOSE ADIMINISTERED: THUS 4 HOURS AFTER THE ADMINISTRATION OF A DOSE OF 40MG/KG DIMETHYLNITROSAMINE, THE INHIBITION OF HNRNA SYNTHESIS REACHED 80%. IN CONTRAST, THE SAME DOSE CAUSED ONLY A …

Estrogen Regulates Vitellogenin Gene Transcription and Messenger-Rna Degradation in Xenopus Laevis Liver
Vitellogenin gene transcription and mRNA degradation rates were measured in Xenopus laevis liver using pulse labeling and pulse chase techniques. Estrogen regulates the accumulation of vitellogenin mRNA through three processes: (1) There is a selective transcriptional activation of the vitellogenin …

An in vitro system for studying the mechanism of action of thyroid hormones
The effect of thyroid hormones on nuclear RNA synthesis was studied in vitro. Results indicated that thyroid hormones added to cell-free rat liver homogenates, in the presence of IMP as a precursor of purine nucleotides and necessary substrates, stimulated orotic acid-6-¹⁴C incorporation into …

Gene Activation in Early Amphibian Development
… processes of cleavage and accompanying protein synthesis are independent of nuclear activity and therefore dependent on substances stored in the maternal cytoplasm. Nuclear function is first required for development beyond the late blastula stage. Gastrulation marks the beginning of rapid …

Nuclear and Plasma Membrane Properties of Macrophage Heterokaryons and Hybrids
… were more prominent and increased nuclear RNA synthesis occurred. Two - three hours after fusion a wave of DNA synthesis took place in the previously dormant macrophage nuclei. DNA synthesis was induced in macrophage nuclei irrespective of the number of macrophage nuclei present per …

MicroRNA-122 and Poly(C)-Binding Protein 2 Bind to the Hepatitis C Virus Genome, Regulating Viral Replication and Genome Structure
Hepatitis C virus (HCV) has a positive-sense RNA genome which is used as the template for both viral translation and negative-strand RNA synthesis. As both processes work in opposite directions on the genome the virus requires a mechanism to coordinate what process is acting on a given copy of …

Determinants of Core Shell Dependent Rotavirus Polymerase Activity
… of childhood mortality in many countries. The RV RNA-dependent RNA polymerase, VP1, synthesizes RNA during viral replication only in the presence of another RV protein, VP2, which comprises the innermost core shell layer of the virion. Though these VP1-VP2 interactions are essential for RV …
