Question

The dUTPase enzyme is used by the African swine fever virus to repair its own DNA, as the cells the virus infects in swine do not express the dUTPase protein. Which of the following is a reasonable explanation for the role of the dUTPase in the virus lifecycle?  Explain your choice in 25 words or less.

    1. The dUTPase is necessary to remove dUTP from the viral genome, as uracil should not be present in DNA
    2. The dUTPase is necessary to remove dUTP from the viral genome, as uridine cannot correctly base pair with adenine-containing bases
    3. The dUTPase is necessary to remove dUTP from the viral genome, as uridine has the wrong sugar component for building DNA
    4. More than one of the above answers is correct
    5. None of the above answers is correct
