An important step in the mechanism proposed for oncogenesis by human papillomaviruses is: A. inactivation of a cellular regulatory gene by human papillomavirus integration into the coding region of the gene. B. transactivation of a normally silent cellular oncogene by a human papillomavirus early protein. C. reversal of keratinocyte differentiation caused by continued active replication and production of progeny human papillomavirus. D. specific binding of certain human papillomavirus early proteins to cellular antioncoproteins. E. induction of a specific chromosome translocation that results in activation of a cellular oncogene.
