RNA Viruses in Virology

Cell death and observable disease symptoms in the host.

DNA is transcribed into mRNA, which is then translated into proteins.

The RF serves as a template, allowing for the creation of multiple copies of the viral genome.

Viruses with a double-stranded RNA genome.

The viral genome begins to actively replicate, leading to a productive infection.

A complementary DNA strand needs to be synthesized to act as a template for mRNA production.

It is first converted to RNA, which then serves as mRNA for protein synthesis.

The host cell initiates defense mechanisms to eliminate the viral dsRNA.

Plus-strand viruses can directly produce mRNA from their genome, while minus-strand viruses need a complementary strand first.

The reactivation of a viral genome in neurons leads to renewed viral replication and subsequent development of disease symptoms.
