Abstract

Herpes simplex virus type 1 DNA isomerization was studied by using a viral mutant, 5B8, lacking the unique SpeI site of its parent, SC16. In coinfected cells, SC16 genomic long segments flanked 5B8 genomes in all possible orientations with similar frequencies. Thus, recombination between progeny of different replication templates is sufficient to explain genomic isomerization.

摘要

利用一种病毒突变体5B8对1型单纯疱疹病毒DNA异构化进行了研究,该突变体缺乏其亲本SC16的独特SpeI位点。在共感染的细胞中,SC16基因组的长片段以相似的频率在所有可能的方向上位于5B8基因组两侧。因此,不同复制模板后代之间的重组足以解释基因组异构化。
