10.11 Summary

    1. 1 phage target cells (sometimeswith their unwitting help)
    2. 2 their tail fibers recognizeand dock to their target cell
    3. 3 their tails (contractile or not)inject the phages genome
    4. 4 the genome directs the cells machinery tomake many copies of components
    5. 5 once the components assemble,the new phage make their exit
    6. 6 ...sometimes in dramatic style
