    What defines a virus?

    Obligate parasite that requires a host cell to replicate.

    What are the main components of a virus?

    Genetic material, capsid, and sometimes a supercapsid.

    How do viruses differ from living cells?

    Lack cellular structure, metabolism, and organelles.

    What happens during the lytic cycle of a bacteriophage?

    The host cell is destroyed, releasing new viruses.

    What is a bacteriophage?

    A virus that specifically infects bacteria.

    What are key properties of viruses?

    Very small, lack metabolism, reproduce only in host cells.

    What distinguishes the lytic cycle from the lysogenic cycle?

    Lytic cycle destroys the host cell immediately; lysogenic cycle integrates into host DNA.

    What occurs during the adsorption phase of a bacteriophage's life cycle?

    The virus attaches to the bacterial cell.

    What is the consequence of a virus having a supercapsid?

    It aids in penetrating host cells.

    What is the role of the tail fibers in a bacteriophage?

    They help the virus attach to the host bacterium.
