摘要：The nucleotide sequence of a region related to the initiation of the reaction in which single-stranded DNA gives rise to the replicative form (complementary strand synthesis) in bacteriophage f1 has been determined. The sequence can be drawn in an extensively base-paired structure, i.e., a single hairpin-helix 55 bases long.
