Mapping of late adenovirus genes by cell-free translation of RNA selected by hybridization to specific DNA fragments.

ABSTRACT

Cytoplasmic RNA, isolated from cells late after infection by adenovirus type 2 and fractionated by hybridization to specific fragments of adenovirus DNA produced by cleavage with the endonuclease R-EcoRI, was used as template for protein synthesis in cell-free mammalian extracts. Each of the R-EcoRI fragments of DNA selects RNA that encodes specific subsets of the viral polypeptides. From the known order of the R-EcoRI fragments, the following partial map is deduced (III, IIIa, IVa2, V, P-VII, IX), (II, P-VI), 100K, IV-where the relative order of the components enclosed in parentheses has not yet been determined.
