Abstract

The present invention provides novel methods of generating a nucleic acid molecule. In certain embodiments, a double stranded nucleic acid chunk is generated from a ladder complex comprising partially complementary oligonucleotides, which chunk is combined with a nucleic acid acceptor molecule. In certain embodiments, the assembled chunk/nucleic acid acceptor molecule complex may be propagated in vivo or in vitro. The present invention also provides improved systems for generating a plurality of nucleic acid molecules that differ at one or more nucleotide positions. In certain embodiments, the plurality of nucleic acid molecules encodes a polypeptide or portion of a polypeptide.
