1. Influenza virus: This virus causes the common flu and is responsible for seasonal epidemics. It has a segmented RNA genome, meaning its genetic material is divided into eight separate RNA molecules.
2. HIV (Human Immunodeficiency Virus): This virus causes AIDS (Acquired Immunodeficiency Syndrome). HIV is a retrovirus, meaning it uses its RNA genome to create a DNA copy that integrates into the host cell's DNA.
3. Ebola virus: This virus causes a severe and often fatal hemorrhagic fever. Ebola virus is a filovirus with a single-stranded RNA genome.
