    • The present invention relates to methods of preparing a DNA comprising steps, wherein (a) a DNA comprising a full length copy of the genomic RNA (gRNA) or an RNA virus; or (b) a DNA comprising one or several fragments of a gRNA of an RNA virus, which fragments code for an RNA dependent RNA polymerase and at least one structural or non-structural protein; or (c) a DNA having a homology of at least 60% to the sequences of (a) or (b); is cloned into a bacterial artificial chromosome (BAC). Additionally, DNAs are provided, which comprise sequences derived from the genomic RNA (gRNA) of a coronavirus which sequences have a homology of at least 60% to the natural sequence of the virus and code for an RNA dependent RNA polymerase and at least one structural or no-structural protein, wherein a fragment of said DNA is capable of being transcribed into RNA which RNA can be assembled to a virion. Further, the use of these nucleic acids for preparation of viral RNA or virions as well as pharmaceutical preparations comprising these DNAs, viral RNAs or virions is disclosed.
    • 本发明涉及制备DNA的方法,包括步骤,其中(a)包含基因组RNA(gRNA)或RNA病毒的全长拷贝的DNA; 或(b)包含RNA病毒的gRNA的一个或几个片段的DNA,其对于RNA依赖性RNA聚合酶和至少一种结构或非结构蛋白的片段编码; 或(c)与(a)或(b)的序列具有至少60%的同源性的DNA; 被克隆到细菌人造染色体(BAC)中。 此外,提供了DNA,其包含衍生自冠状病毒的基因组RNA(gRNA)的序列,该序列与病毒的天然序列具有至少60%的同源性,并编码RNA依赖性RNA聚合酶和至少一种结构 或无结构蛋白,其中所述DNA的片段能够被转录成RNA,所述RNA可以组装成病毒粒子。 此外,公开了使用这些核酸来制备病毒RNA或病毒粒子以及包含这些DNA,病毒RNA或病毒粒子的药物制剂。
