Infectious particles with S values of 114 and 132 were isolated from cells infected with bacteriophage phi chi 174. Electron micrographs of the 132S particle revealed a spherical structure with a diameter of about 40 nm. The 114S particle had spikelike projections and a diameter of about 32 nm. The 132S particles could be converted to 114S particles in vitro. However, pulse and pulse-chase experiments indicated no precursor-product relationship between these two particles in vivo.
从感染噬菌体φX174的细胞中分离出了沉降系数为114和132的感染性颗粒。132S颗粒的电子显微镜照片显示其为直径约40纳米的球形结构。114S颗粒有刺状突起,直径约32纳米。132S颗粒在体外可转化为114S颗粒。然而,脉冲和脉冲追踪实验表明这两种颗粒在体内不存在前体-产物关系。
