病毒没有细胞结构,一般由蛋白质外壳和核酸组成,有的病毒还含有脂质和多糖构成的包膜或囊膜。根据病毒的遗传类型可将其分为:双链DNA病毒、单链DNA病毒、双链RNA病毒和单链RNA病毒。高中生物教材中对常见的病毒都有详细的叙述和介绍。但随着日常生活中出现的由病毒引起的传染病逐渐增多,学生需要了解更多的有关病毒的知识。本文对病毒相关的知识做了简单介绍,并对病毒知识理解中的几个误区进
The virus has no cell structure, usually by the protein shell and nucleic acid composition, and some viruses also contain lipid and polysaccharide capsule or capsule. According to the genetic type of the virus it can be divided into: double stranded DNA virus, single stranded DNA virus, double stranded RNA virus and single stranded RNA virus. High school biology textbooks have a detailed description and introduction of common viruses. But as the number of infectious diseases caused by viruses in everyday life increases, students need to know more about the virus. This article made a brief introduction of the virus-related knowledge, and several misunderstandings in the virus knowledge
