The parvovirus genome is a linear, single-stranded DNA molecule with double-stranded hairpin termini. The 3' terminus can serve in vitro as a self-primer for the synthesis of a double-stranded viral DNA intermediate. We have sequenced the nucleotides in the 3' terminus and propose a model for the secondary structure of the terminus and the in vitro origin of replication for the complementary viral DNA strand.
细小病毒基因组是一个线性单链DNA分子,其末端为双链发夹结构。3'末端在体外可作为自身引物,用于合成双链病毒DNA中间体。我们已对3'末端的核苷酸进行了测序,并提出了该末端二级结构以及互补病毒DNA链体外复制起点的模型。
