Deletion mutants of human wart virus were found to occur occasionally in the virus population transmitted in vivo, although the majority of virion DNA molecules were homogeneous in length and base sequence. Human wart virus DNA was 1.48 times as long as nondefective simian virus 40 DNA.
虽然大多数病毒粒子DNA分子在长度和碱基序列上是均一的,但在体内传播的人乳头瘤病毒群体中偶尔会发现人乳头瘤病毒的缺失突变体。人乳头瘤病毒DNA的长度是非缺陷型猿猴病毒40 DNA的1.48倍。
