Early RNA of adenovirus type 3 in permissive and abortive infections.

Early adenovirus type 3 cytoplasmic polyadenylated RNAs from HeLa and BHK-21 cells were detected and mapped on the viral genome by gel blotting and hybridization techniques. The sizes and locations of the 16 adenovirus type 3 RNAs were identical in the two cell types, although relative molarities of the various RNA species differed. Each of the early adenovirus type 3 RNAs was associated with polysomes in both cell types, suggesting that the abortive infection of hamster cells does not result from a defect in early adenovirus type 3 mRNA biosynthesis. No RNAs from regions transcribed late in infection of permissive cells were detected in BHK-21 cells.
