单词辨析
百科
1. 病毒（英文名：Biological virus），必须在活细胞内寄生并以复制方式增殖的非细胞型生物。 病毒是一种非细胞生命形态，它由一个核酸长链和蛋白质外壳构成，病毒没有自己的代谢机构，没有酶系统。个体微小，结构简单，只含一种核酸（DNA或RNA），必须在活细胞内寄生。因此病毒离开了宿主细胞，就成了没有任何生命活动、也不能独立自我繁殖的化学物质。它的复制、转录、和转译的能力都是在宿主细胞中进行，当它进入宿主细胞后，它就可以利用细胞中的物质和能量完成生命活动，按照它自己的核酸所包含的遗传信息产生和它一样的新一代病毒。 按照寄主类型，病毒可分为动物病毒、植物病毒和细菌病毒等。动物病毒主要侵染脊椎动物和节肢动物；这包括多种人类常见疾病的病原体。一部分主要侵染其他脊椎动物和节肢动物，借节肢动物来传播的病毒也可在人体造成严重疾病如多种脑炎。植物病毒主要侵染有花植物，常给人类带来经济损失。细菌病毒又称噬菌体，现已知寄生于细菌的病毒也可间接造成人类疾病，如白喉毒素蛋白实际是由在菌体寄生的病毒指导合成的。噬菌体还是分子生物学的良好实验材料，许多分子生物学的重大发现都是得自噬菌体实验。
