MDCAT Biology MCQ #45

  1. Question 1

    Q1. A bacteriophage infects E. coli but does not immediately lyse the cell, instead persisting through generations. Which life cycle is being exhibited?

    • A) Lytic cycle
    • B) Lysogenic cycle
    • C) Spontaneous induction
    • D) Transduction

    Answer: Lysogenic cycle

    Explanation: In lysogeny, the viral DNA integrates into the host chromosome as a prophage. The lytic cycle is tempting but involves immediate host cell destruction.
