Quizplus · Accepted Answer

During the lytic phase, the early gene products of the bacteriophage will inhibit the host genes in order to take over the cellular machinery and promote the replication of viral genes. On the other hand, the early gene products will also stimulate the expression of the late genes, which encode for structural proteins needed to assemble new viral particles. Therefore, the best answer is D.
