Around 74% of the nucleotides in the hepatitis D virus genome are complementary, meaning they bind to one another. This compresses the circular genome into a rod-like form (Figure 2).

Viruses, then, may have existed before bacteria, archaea, or eukaryotes (Figure 4; ... Could today's single-stranded RNA viruses be descendants of these precellular RNA molecules?

New research has discovered that the Herpes virus actually takes control of key RNA functionality and changes human DNA in ...

Double-stranded (ds)RNA viruses. As shown in part a of the figure, virus attachment and endocytosis deliver a virion core that contains viral genomic dsRNA and viral RNA polymerase ...

A study published in Science today (April 7) describes thousands of newly discovered RNA viruses and doubles the number of phyla in which they’re grouped from 5 to 10.. A team led by Ohio State ...

(Left) As in Figure 5, RNA has a hydroxyl group that is 5 atoms (just the right bonding distance) from the phosphate group (blue arrow) that holds RNA (and DNA) together. This promotes a cyclization ...

RNA is the molecule that reads the genetic information stored in DNA. It's critical for the proper functioning of cells, and ...

The expression of symptoms of viral infections is a byproduct of complex virus-host molecular pathways. These remain largely unknown, especially in the case of fungus-virus pathogen systems.

RNA viruses — including coronaviruses — have genetic material consisting of a single ribonucleic acid (RNA) strand, as opposed to double-stranded DNA in DNA viruses, like Herpes viruses.

FIGURE 3: Spike comparison between BA.2.86 ... N1708S, A1892T, and in some instances, K1155R and T1269I. NSP3 is one of the most active proteins in the virus, playing roles in viral RNA ...

Retroviruses are RNA viruses that are characterized by the integration of their RNA into the host genome after reverse transcription. This leads to prolonged expression of the gene of interest.

Scientists have identified more than 100,000 RNA viruses that have never been seen before, a new study has revealed. An international team of researchers has discovered novel and diverse groups of ...
