In an ______________ plasmid, replication occurs in two stages. In the first stage, the double stranded circular plasmid DNA replicates to form another double-stranded circular DNA and a single-stranded circular DNA, In the second stage, the complementary strand is synthesized on the single-stranded DNA to make another double-stranded DNA.
