title: On the origin of the gene coding for an influenze A virus nucleocapsid protein.
abstract: The gene coding for the nucleocapsid protein NP of the influenza A virus recombinant strain 413 1,1 was characterized biochemically by molecular hybridization and fingerprint analysis. The data presented suggest that this NP gene has evolved by intracistronic recombination between NP genes of virus N and the fowl plague virus temperature-sensitive mutants ts 19.
