Quiz Viruses %CODE1% Name: Viruses True/False Indicate whether the sentence or statement is true or false. TF 1. Although viruses do not consist of cells, biologists consider them to be living because they are capable of reproduction. TF 2. Some viruses have a membranous envelope surrounding the protein coat that helps them gain entry into host cells. TF 3. Viruses consist of RNA or DNA surrounded by a coat of protein. TF 4. Prions are the smallest known particles that are able to replicate. TF 5. A virus can only reproduce by controlling a cell. TF 6. Once a virus enters either a lytic or a lysogenic cycle, it cannot change to the opposite type of cycle. TF 7. Prophages and proviruses can both enter lytic cycles and destroy host cells. TF 8. People can contract the influenza virus more than once because the virus tends to mutate rapidly, avoiding the actions of the immune system. TF 9. Smallpox is caused by bacteria. TF 10. Chickenpox and shingles are caused by the same virus. Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ABCD 11.

A prophage differs from a provirus in that a. a prophage contains DNA, while a provirus contains RNA. b. a prophage is formed during a lysogenic cycle, while a provirus is formed during a lytic cycle. c. a prophage contains DNA found in the infecting virus particle, while a provirus contains DNA produced from viral RNA. d. a prophage becomes integrated into a host cell’s DNA, while a provirus cannot become integrated into a host cell’s DNA. ABCD 19. Which of the following is not a virus linked to cancer? a. Ebola c. hepatitis B b. human papillomavirus d. Epstein-Barr ABCD 20. Which of the following human activities is most closely associated with emerging viruses? a. absence of a vaccination program c. clearcutting of forests b. crowded living conditions d. eating uncooked meat
