Ad2(+)ND(1), a nondefective adenovirus 2 (Ad2)-simian virus 40 (SV40) hybrid virus, has been previously shown to contain a small segment of the SV40 genome covalently linked to Ad2 deoxyribonucleic acid (DNA). The SV40 portion of this hybrid virus has been characterized by relating the SV40-specific ribonucleic acid (RNA) sequences transcribed from the Ad2(+)ND(1) DNA to those transcribed from the DNA of SV40 itself. RNA-DNA hybridization-competition studies indicate that the SV40 component of Ad2(+)ND(1) consists of some, but not all, of that part of the SV40 genome which is transcribed early, i.e., prior to viral DNA replication, in SV40 lytic infection.
Ad2(+)ND(1)是一种无缺陷的腺病毒2型(Ad2)-猴病毒40型(SV40)杂交病毒,先前已证明它含有一小段与Ad2脱氧核糖核酸(DNA)共价连接的SV40基因组。通过将从Ad2(+)ND(1) DNA转录的SV40特异性核糖核酸(RNA)序列与从SV40自身DNA转录的序列进行关联,对这种杂交病毒的SV40部分进行了表征。RNA-DNA杂交竞争研究表明,Ad2(+)ND(1)的SV40组分由SV40基因组中在SV40裂解感染中早期转录(即在病毒DNA复制之前)的部分组成,但并非全部。
