What effect would a Q- mutation have on phage lambda infection?
◦ No effect, infection would proceed as normal to either lytic or lysogenic pathway
◦ Lytic pathway blocked, only lysogeny possible
◦ Lysogenic pathway blocked, only lytic pathway possible
◦ Complete abolishment of infection, neither lytic nor lysogenic pathway possible
◦ Higher levels of phage production than in wild-type phage
