RESUMO

From human KB cells productively infected with adenovirus type 12, mRNA and stable nuclear RNA were isolated late (42 h) after infection. Using restriction endonuclease fragments of adenovirus type 12 DNA, mRNA and stable nuclear RNA sequences were mapped on the viral genome. Late after infection, preferentially the r (= rightward) strand is transcribed into stable nuclear RNA, whereas the l (= leftward) strand is expressed only to a minor extent. Adenovirus type 12-specific mRNA originates from the following sections on the viral genome: 0 to 0.11, 0.18 to 0.20, 0.27 to 0.49, 0.56 to 0.63, 0.68 to 0.84, and 0.89 to 0.92 fractional length units on the r strand and 0.11 to 0.16, 0.22 to 0.27, 0.50 to 0.54, 0.62 to 0.66, 0.855 to 0.865, and 0.93 to 1.0 fractional length units on the l strand. Self-complementary viral RNA isolated at 42 h postinfection anneals to 70 to 80% of each strand of the viral genome.
