The goal of this lesson is to introduce learners to the lytic and lysogenic cycles of T4 and lambda bacteriophages, respectively, using student-centered pedagogies. Bacteriophages will viruses that infect bacteria additionally are either virulent or temperate; virulent phages can only undergo the lytic cycle, which results in death of the host cell, … WebThus, SM represents the first EBV gene product expressed during the lytic cycle that can prevent PKR activation. In addition, the RXP repeat segment appears to be a conserved herpesvirus motif capable of associating with dsRNA and modulating activation of the PKR kinase, a molecule important for the control of translation and the cellular antiviral response.
