Abstract

Double-stranded cDNA was synthesized from hepatitis A virus (HAV) RNA and inserted into the Pst I site of pBR322. Restriction endonuclease digestion and cross-hybridization of fragments yielded a map of overlapping cloned cDNAs that included at least 99% of the viral genome. Molecular clones containing HAV cDNA were identified by hybridizing cloned cDNA to electrophoretically resolved RNA from uninfected and HAV-infected tissue culture cells. Cloned cDNA probes specifically hybridized to RNA from infected cells, and the predominant species identified had the characteristic genomic length of picornaviral RNA (~7,500 nucleotides). A partial sequence from the 3' end of the genome revealed 414 bases in an open reading frame followed by two closely spaced stop codons, a 60-base noncoding region, and a tract of poly(A).
