The genomes of viruses in family Geminiviridae are single stranded DNA, and their replication strategies are distinctly different from that of RNA viruses. The geminiviruses use the replication machinery of the host and hence have been presumed to have a high fidelity of replication. 双生病毒(geminiviruses)是一类单链DNA病毒,其复制方式有别于植物RNA病毒,他们是利用寄主植物的DNA复制酶复制,理论上其忠实性远高于RNA病毒。
The genome of influenza A virus is comprised of eight separate segments of single-stranded, negative-sense RNA. A型流感病毒基因组为单股负义RNA,分为8个片段。
Viroids are single stranded, circular and non-coding pathogenic RNAs that can infect higher plants. 类病毒是一类能够侵染高等植物的单链闭合环状,无编码功能的RNA分子。
MicroRNAs ( miRNAs) are a set of small single stranded non-coding RNA molecules that serve as important negative gene regulators. MicroRNAs(miRNAs)是一组小的单链非编码RNA分子,是重要的基因负调控因子。
