Genetic Analysis of a Baculovirus, Autographa californica Nuclear Polyhedrosis Virus I. Isolation of Temperature-Sensitive Mutants and Assortment into Complementation Groups.

abstract：:Previous analysis of hepatitis B virus (HBV) indicated base pairing between two cis-acting sequences, the 5' half of the upper stem of epsilon and phi, contributes to the synthesis of minus-strand DNA. Our goal was to identify other cis-acting sequences on the pregenomic RNA (pgRNA) involved in the synthesis of minus-...
