A new approach to create chimeric genes by directed exchange of oligonucleotide fragments was developed. By oligonucleotide-directed mutagenesis a few deletion mutants of the influenza virus hemagglutinin (HA) gene were obtained. These variants of HA gene contain unique restriction sites in DNA regions coding for the A and B epitopes of the HA molecule. The obtained special vectors may be used for cloning DNA fragments coding for new amino acid sequences in internal sites of the HA gene.
