(RNA) is a molecule found in cells that does many tasks for the human body, including the transformation of DNA information into proteins. Learn about RNA viruses and their replication strategies. Explore the features and viruses of RNA, such as double-stranded, positive and negative sense, ...
What is a positive-sense RNA virus? What is a segmented RNA genome? Do polioviruses possess a positive strand RNA genome? What is RNA sequencing What do DNA and RNA have in common? What type of genome does a RNA virus have? What are the benefits of mitochondrial DNA and ribosomal RNA...
Positive-sense viral RNA is similar to mRNA and thus can be immediately translated by the host cell. Negative-sense viralRNA is complementary to mRNAand thus must be converted to positive-sense RNA by an RNA polymerase before translation. Which of the following diseases is caused by a virus w...
Viruses can be encoded in a variety of ways.Rotavirusesare based on a double strand of RNA, for example. Coronaviruses have a single strand of RNA, which is 'positive sense', as in it can be translated directly into new proteins.Influenzahas negative sense RNA, meaning it needs an extra...
Next-generation sequencing (NGS) is a technology for determining the sequence of DNA or RNA to study genetic variation associated with diseases or other biological phenomena. Introduced for commercial use in 2005, this method was initially c...
As positive-sense RNA viruses, pestivirus replication occurs via a semi-conservative model [14] using a double-stranded (ds) RNA template to synthesize plus-strand, genomic viral RNA. Accordingly, replicative forms (RF) and replicative intermediates (RI) were detected in BVDV-infected cells, and...
Coronaviruses are enveloped, single-stranded, positive-sense RNA viruses that infect a wide variety of species, including people, livestock and companion animals. These viruses display exceptional genetic plasticity, driven by the accumulation of point mutations and recombination events. This genetic ...
Like other coronaviruses, SARS-CoV-2 is an enveloped virus with a non-segmented, single-stranded, positive-sense RNA filament [51,52]. The virus contains a nucleocapsid with helical symmetry and its viral particles are composed of four structural proteins: glycoprotein S (spike), transmembrane ...

Mammalian cells have evolved specialized mechanisms to sense and repair double-strand breaks (DSBs) to maintain genomic stability. However, in certain cases, the activity of these pathways can lead to aberrant DNA repair, genomic instability and tumorigenesis. One such case is DNA repair at the na...
