(1pt) To transfer DNA from one bacterium to another What mistakes made during the P1 lytic cycle are researchers able to capitalize on to perform a transduction? (1pt) 0.3% of the time, P1 mistakenly packages chromosomal DNA instead of its own What process occurs during transduction to allow packaged DNA from the P1 (phage) to integrate into the host chromosome? (1pt) Homologous Recombination Name the 4 steps of the lytic cycle, including a brief description of each. (4pts) 1. Recognition: phage recognizes host by the tail fibers binding to chemical groups on host cell surface 2. Injection/Penetration: lysozyme in tail erodes cell wall to weaken it; the sheath contracts and punches a hole in the wall; as the sheath contracts, viral nucleic acid is pumped through the...
