病毒在科学上引起了很多的争论:如发现了反转录过程和自我复制,补充了中心法则,又发现了朊病毒,对中心法则又发起了冲击,挑战了生命的定义。新课标高中生物教材中也多次说到病毒:基因工程中用作运载体;动物细胞工程中用作促融;在免疫中作抗原。病毒核酸的类型病毒的核酸包括双链DNA(dsDNA)、 The virus has caused a lot of controversy in science: such as the discovery of the process of transcription and self-duplication, complementing the central principle, and the discovery of prions, which have launched an attack on the central law and challenged the definition of life. New Curriculum High School biology textbooks also repeatedly said that the virus: genetic engineering as a carrier; animal cell engineering for the promotion of financial; antigens in immunity. Nucleic acids of the viral nucleic acid type virus include double stranded DNA (dsDNA),
