ABSTRACT
HA20, a mutant of Bacillus subtilis phage SPO1, is deficient in both DNA replication and late transcription. HA20 contains mutations in two different genes, which suggested that the two effects might be caused independently. However, single-mutation derivatives, affected only in gene 27, were deficient for both activities. Thus, a single mutation apparently affects both DNA replication and late transcription.
