DNA virus maturation

Journal of Cellular Physiology, 1969
Maturation of bacterial viruses requires the formation of mature viral nucleic acid in the form found in progeny virus particles, the “packaging” of this viral nucleic acid within a capsule, and the assembly of “packaged” nucleic acid with the accessory structures necessary for infectivity.

Studies on vaccinia virus DNA

Virology, 1967
Abstract A method has been developed for the isolation of intact DNA genomes from purified vaccinia virions. A molecular weight of 150 × 106 to 170 × 106 daltons was determined for vaccinia virus DNA molecules by zone centrifugation and electron microscopy, respectively.

The Insertion of DNA into Vaccinia Virus

Science, 1976
Cells infected with vaccinia virus in the presence of hydroxyurea (HU), which blocks DNA replication, were examined in thin sections by electron microscopy at intervals after removal of HU. Dense, fibrillar material was observed at the orifice formed just before closure of the membrane constituting the envelope of the immature form of the virus.

DNA virus replication

Journal of Clinical Virology, 2000
Abstract DNA viruses have always been the most important model systems for eukaryotic DNA replication. Add to this the clinical significance of these human pathogens- 99% of the population of the world is infected with at least one of the viruses discussed in this volume (hepatitis B virus, Eptstein Barr virus or herpes simplex virus)

Virus DNA and host DNA in polyoma virus-infected cells at high temperature

Virology, 1972
Abstract Incubation of mouse kidney (MK) cells at 41.6 ± 0.1° led to a rapid inhibition of DNA synthesis. Infection with the SP 2 mutant of polyoma virus (PV) at 41.6° induced the cells to synthesize DNA again. However, production of infectious SP 2 DNA or infectious virions was reduced under these conditions.

Simian varicella virus DNA shares homology with human varicella-zoster virus DNA

Virology, 1984
Delta herpesvirus (DHV) and Medical Lake Macaque (MLM) virus are cell-associated simian herpesviruses that cause varicella-like disease in nonhuman primates, and are antigenically related to human varicella-zoster virus (VZV). The results of studies designed to determine if homology exists between the DNA of DHV and MLM and the DNA of VZV are reported ...

Mode of replication of pseudorabies virus DNA

Virology, 1964
Pseudorabies (Pr) virus DNA is double-stranded: its buoyant density in cesium chloride is that expected of double-stranded DNA with the same content of guanine and cytosine (73 moles %); furthermore, this DNA does not react with formaldehyde and its buoyant density shows the expected increase after heat denaturation.

Presence of DNA in Rous Sarcoma Virus

Nature, 1970
DNA has been isolated from the virion of Rous sarcoma virus. It consists of two components which seem to correspond to the two species of DNA synthesized in vitro by the recently identified virion RNA-dependent DNA polymerase.

Electron microscopy of vaccinia virus DNA

Journal of Molecular Biology, 1968
Abstract Vaccinia virus DNA molecules, isolated mostly intact from purified virions, were studied by electron microscopy. Molecules prepared on water were found to attain different configurations, whereas molecules prepared in ammonium acetate were fully stretched.

The mode of replication of vaccinia virus DNA

Virology, 1978
Abstract Synthesis of vaccinia virus DNA was studied by following the incorporation of [3H]thymidine in the cytoplasm of infected cells. During short pulses (1–5 min) the radioactive precursor was incorporated into single-stranded DNA fragments that sedimented as 10–12 S in neutral sucrose gradients.
