oncogenic virus

He assumed that the tumour cells, if they contained an oncogenic virus, should harbour viral DNA integrated into their genomes.

他认为，肿瘤细胞，如果它们载有致癌病毒，应港湾病毒DNA整合到它们的基因组。

They are oncogenic DNA virus with icosahedral capsids 40 nm~ 45 nm in diameter, containing three to four viral proteins and double strand, covalently closed, circular genomes approximately 5 000 bp in size.

病毒无囊膜，直径40nm～45nm，有3种～4种衣壳蛋白，基因组为约5000对核苷酸组成的双链闭合环状DNA。

Human papillomavirus is an oncogenic DNA virus and has more than 90 subtypes. High risk types ( HPV 16, 18, 33) are associated with many kinds of malignant neoplasms of head and neck.

人乳头状瘤病毒是一种致瘤性DNA病毒，在其90个亚型中以高危型HPV16，HPV18，HPV33等与人类头颈部恶性肿瘤关系密切。

The results indicated that there was no oncogene in L783-MuLV genome, L783-MuLV belonged to slow oncogenic virus.

这说明，L783小鼠白血病病毒基因组中不含有致癌病毒基因，此病毒属于慢性致瘤性逆转录病毒。
