Resource summary

Question Answer
Method Of Transfer Transfer between 2 cells by way of a bacteriophage
Generalised Transformation- Cycle Type Lytic
Generalised Transformation- Stage 1 Phage injects DNA
Generalised Transformation- Stage 2 Phage enzymes degrade host DNA
Generalised Transformation- Stage 3 New phages are made that may contain host DNA
Specialised Transduction Lysogenic phage exists from host genome and carries adjacent host genes with it
Phage Conversion Aleration of host cell phenotype by lysogenation
SScPI's Stapylococcal Superantigen-Carrying Pathogenicity Islands
SScPI- Location Specific sites with no integral method of transfer
SScPI- Transfer Requires lysogenic pahge
SScPI- StI Required for stable genome insertion (mutation allows SScPI to be transferred)
SScPI- Transferance Requirments StI mutation or lysogenic phage (SScPI will hijack lysogenic phages for packaging/exit)
