Viral RNA Synthesis

2014
This chapter summarizes what is known about how a single viral RNA molecule can be selectively amplified into thousands of RNA progeny in infected cells. It specifically provides the roles of viral proteins and RNA sequences in RNA replication, and describes the kinetics and products of RNA replication in infected cells. Next, it explains the sites and

Structural organization of viral RNA-dependent RNA polymerases

Biochemistry (Moscow), 2013
This review describes available data on the structure of viral RNA-dependent RNA polymerases (RdRP) obtained from X-ray analysis and discusses the functional significance of the structural elements of these enzymes. Because most of the studies done to date relate to RdRP structures of picorna-, flavi-, and caliciviruses, here we consider mostly the ...

RNA interference – small RNAs effectively fight viral hepatitis

Liver International, 2004
Abstract: RNA interference (RNAi) is the process of sequence‐specific gene silencing, initiated by double‐stranded RNA that is homologous in sequence to the target gene. This unique phenomenon has been extensively investigated during the last few years not only in the context of its mechanism and its possible role in the regulation of gene expression ...

Viral RNA-Dependent RNA Polymerases: A Structural Overview

2018
Most emerging and re-emerging human and animal viral diseases are associated with RNA viruses. All these pathogens, with the exception of retroviruses, encode a specialized enzyme called RNA-dependent RNA polymerase (RdRP), which catalyze phosphodiester-bond formation between ribonucleotides (NTPs) in an RNA template-dependent manner.

Electron Microscopy of Viral RNA

1981
The electron microscopy of nucleic acid molecules has become a routine tool in the analysis of genome structure and function. This is primarily due to the availability of simple reliable methods for the visualization of single- and double-stranded DNA and RNA molecules, of RNA-DNA hybrids, and of nucleic acid-protein complexes.

Plant RNA Silencing in Viral Defence

2011
RNA silencing is described in plants and insects as a defence mechanism against foreign nucleic acids, such as invading viruses. The RNA silencing-based antiviral defence involves the production of virus-derived small interfering RNAs and their association to effector proteins, which together drive the sequence specific inactivation of viruses.
