Abstract：
:The origin of DNA replication of bacteriophage f1 consists of two functional domains: 1) a "core region", about 40 nucleotides long, that is absolutely required for viral (plus) strand replication and contains three distinct but partially overlapping signals, a) the recognition sequence for the viral gene II protein, which is necessary for both initiation and termination of viral strand synthesis, b) the termination signal, which extends for 8 more nucleotides on the 5' side of the gene II protein recognition sequence, c) the initiation signal that extends for about 10 more nucleotides on the 3' side of the gene II protein recognition sequence; 2) a "secondary region", 100 nucleotides long, required exclusively for plus strand initiation. Disruption of the "secondary region" does not completely abolish the functionality of the f1 origin but does drastically reduce it (1% residual biological activity). This region, however, can be made entirely dispensable by mutations elsewhere in the phage genome.
