About This Quiz

The virus is one of the organisms you’ll learn about under the scope of microbiology, but you’ll probably know already that these are a much different kettle of fish from bacteria, given that they’re harder to get rid of with viral infections like influenza and the common cold is just that, common. What can you tell us about the structure of these viruses and how they’re able to replicate? Let’s find out!

    What is the outside, protein coat on a virus called?

    • Genetic material

    • Capsid

    • Envelope

    • Tail fibers

    Correct Answer
    A. Capsid
    Explanation
    The outside, protein coat on a virus is called the capsid. The capsid is made up of protein subunits that protect the virus's genetic material. It provides structural support and helps the virus attach to host cells. The capsid can have various shapes, such as helical or icosahedral, depending on the type of virus.

    Viruses are destroyed by antibiotics.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Antibiotics are designed to kill or inhibit the growth of bacteria, not viruses. Viruses are different from bacteria in terms of structure and life cycle, so antibiotics are ineffective against them. Viral infections are typically treated with antiviral medications or other supportive measures, as antibiotics do not have any effect on viruses. Therefore, the statement "Viruses are destroyed by antibiotics" is false.

    Virulent viruses reproduce by

    • Mitosis

    • The lysogenic cycle

    • The lytic cycle

    • Binary fission

    Correct Answer
    A. The lytic cycle
    Explanation
    The lytic cycle is the correct answer because it is the process by which virulent viruses reproduce. In the lytic cycle, the virus infects a host cell, takes over the cell's machinery, and uses it to produce multiple copies of itself. Eventually, the host cell bursts open (lyses), releasing the newly formed viruses to infect other cells. This cycle allows the virus to rapidly replicate and spread throughout the host organism.

    Viral DNA that is incorporated into a host cell's chromosome is called a

    • Provirus

    • Plasmid

    • Party animal

    • Bacteriophage

    Correct Answer
    A. Provirus
    Explanation
    A provirus is viral DNA that has been integrated into the host cell's chromosome. This integration allows the viral DNA to be replicated along with the host cell's DNA during cell division. The provirus remains dormant within the host cell until it is activated, at which point it can initiate the production of new viral particles. This term is commonly used to describe the DNA of retroviruses, such as HIV, which integrate into the host cell's genome.
