The pattern of binding of repressor and Cro to these sites determines whether the phage grows lytically or lysogenicaly. Launch the molecular model of the temperate bacteriophage repressor to explore its structure. Then, answer the questions. Launch molecular model Part A The pattern of binding of repressor and Cro to these sites determines whether the phage grows lytically or lysogenically. Which of the following accurately describes the regulation of lytic and lysogenic cycles by bacteriophage repressor? a. In the lysogenic cycle, Cro protein is produced, preventing the expression of the repressor protein; genes for viral replication are expressed. In the lytic cycle, repressor protein is produced, preventing the expression of Cro genes for viral replication are not expressed. b. In the lysogenic cycle, both repressor and Cro proteins are produced: genes for viral replication are expressed. In the lytic cycle, there is no expression of either repressor or Cro protein: genes for viral replication are not expressed c. In the lysogenic cycle, there is no expression of either repressor or Cro protein; genes for viral replication are not expressed. .In the lytic cycle, both repressor and Cro protein are produced; genes for viral replication are expressed. d. In the lysogenic cycle, repressor protein is produced, preventing the expression of Cro and genes for viral replication. In the lytic cycle, Cro protein is produced, preventing the expression of repressor protein
