Abstract
  1. The sucrose-gradient pattern of (32)P-labelled RNA synthesized in actinomycintreated baby-hamster kidney cells infected with foot-and-mouth-disease virus depends greatly on the period of labelling. 2. Fractions are formed in infected cells that sediment at 12-20s and have the same base composition as similar fractions found in non-infected cells that have been treated with actinomycin. 3. In the presence of guanidine, which completely inhibits viral RNA synthesis, these fractions are labelled to a greater extent than in non-infected cells.
摘要
  1. 在感染口蹄疫病毒的仓鼠肾细胞中,经放线菌素处理后,(32)P 标记的 RNA 合成的蔗糖梯度图谱在很大程度上取决于标记的时期。

  2. 在感染细胞中形成了在 12-20s 处沉降的级分,并且其碱基组成与用放线菌素处理的未感染细胞中的类似级分相同。

  3. 在胍存在的情况下,完全抑制病毒 RNA 合成,这些级分的标记程度比未感染细胞更高。
