Transcription of the Genome of Adenovirus Type 12

Abstract

In human KB cells productively infected with adenovirus type 12, viral DNA replication starts between 12 and 14h postinfection. Virus-specific, polysome-associated mRNA was investigated early (6-8h) and late (26-28h) after infection. Most of the viral mRNA was polyadenylated and accounted for 0.46% and 24.1% of the mRNA synthesized early and late postinfection, respectively. The viral-specific mRNA isolated both early and late after infection falls into several distinct size-classes, ranging in molecular weights between 0.3X10(6) and 1.5X10(6) for the early RNA and between 0.6X10(6) and 2.3X10(6) for the RNA synthesized late in the infection.
