1. RecBCD enzyme and Chi recombination hotspots as determinants of self vs. non-self: Myths and mechanisms
    1. Introduction
    2. Chi is more frequent in many bacterial species and E. coli phages and plasmids than in E. coli itself
    3. Chi is active in "foreign" species
    4. Is Chi "over-represented" in E. coifs genome?
    5. "Chi" sequence of S. aureus also comports with its codon usage
    6. Temperate phage P1 contains 50 Chi sites, likely uses them to its advantage, and appears to select for Chi as a recombination hotspot
    7. A myth: "Chi converts RecBCD from phage destruction to DNA repair"
    8. An observation: RecBCD destroys DNA in E. coil only if it cannot recombine
    9. Mechanisms employing RecBCD that do distinguish self vs. non-self DNA
    10. Conclusion: Telling self from non-self is complex
    11. Methods of data analysis
