Molecular formula : CAS :
nature : single stranded DNA and RNA virus replication process, as intermediate product formed by double-stranded form. It contains through hydrogen bonding to the complementary strand of the original virus nucleic acid chain. For example, E. coli virus ф × 174, from its genomic DNA single-strand ring composed of a virus - or (+) strand DNA. After infection of host cells, DNA replication, by the pro-generation single-chain circular DNA as a template to guide complementary chain (-) strand DNA synthesis, and produces a double-stranded circular DNA molecules shall be replicating (RF) elements. This ring (+/-) double-stranded DNA, as a large number of self-reproduction copy and then to (-) as a template through the chain roller Central synthesize a large number of copies (+) strand DNA, packaged into viral particles.
