Question

Which of the following is/are true of viruses? They are not cells They are obligate intracellular parasites. They cannot reproduce independently Two of these All of these TRUE OR FALSE? A low cost method of producing viruses for vaccines is to grow them in chicken egg cultures TRUE OR FALSE? A latent virus infection does not have detectable symptoms until late in the advancement of disease. TRUE OR FALSE? Viruses may be tissue specific, recognizing receptor sites only on certain cells. TRUE OR FALSE? Viruses can be grown in a cell culture in the laboratory TRUE OR FALSE? A latent viral infection has a quick onset. TRUE OR FALSE? All viruses have a nucleic acid core, a capsid enclosing the core, a derived from the host's cell membrane. TRUE OR FALSE? Viruses are called obligate intracellular parasites because they require a cellular host to reproduce Viruses can be described as: nd an outer envelope Being infectious Being seen clearly with the light microscope Infecting only prokaryotic cells Being lethal for all cells they infect More than one of these An example of a latent virus infection is: SSPE Genital herpes Influenza Mumps

Explanation / Answer

1. All of these
Virus are not cells they not cell it ifecte the other cells.
They are obligate parasite, need host for reproduce.

2. True
Chicken egg culture is the low cost method to culture the virus

3. True

4. True - Virus only infect certain tissues based on receptor sites

5. True

6. False - Latent virus transfer it genome to host and become lysogen.

7. False - Not all virus have capsid, envelope

8. True

9. Being infectious
not seen by light microscope, Infect eukaryotes also
not lethal to all cells they infect undergoes lysogency.

10.Genital herpes.
