您要查找的是不是：
- parental viral DNA 亲代病毒DNA
- When SV40 enters a cell, it produces T antigen, which functions to trigger viral DNA replication. 当SV40病毒进入细胞时会产生T抗原，它的作用是触发病毒DNA繁殖。
- Vaccinia virus B1R gene product acts as protein kinase with an essential role in viral DNA replication. 牛痘病毒B1R基因产物是一个蛋白激酶，在病毒的DNA复制中起着重要作用。
- Soon the viral DNA directs the cell to make copies of the viral DNA, synthesize viral proteins and combine the two into billions of new adenoviruses. 不久，病毒的DNA就会指挥细胞制造病毒DNA及合成病毒蛋白，并将两者结合，形成数十亿个新的腺病毒。
