1. A method for in vitro cloning of a nucleic acid of interest, comprising:

  • (a) mixing in vitro a first vector comprising at least a first recombination site and a second vector comprising at least a second recombination site, wherein said first and/or second vector further comprises a nucleic acid of interest;

    (b) incubating said mixture in the presence of at least one recombination protein under conditions sufficient to cause recombination of at least said first and second recombination sites, thereby producing a chimeric nucleic acid molecule comprising said nucleic acid of interest;

    (c) contacting one or more hosts with said mixture; and

    (d) selecting for a host comprising said chimeric nucleic acid molecule, and selecting against a host comprising said first vector and against a host comprising said second vector, thereby cloning said nucleic acid of interest.
