1题目根据遗传物质的化学组成,可将病毒分为RNA病毒和DNA病毒两种类型,有些病毒对人类健康会造成很大危害,通常,一种新病毒出现后需要确定该病毒的类型。假设在宿主细胞内不发生碱基之间的相互转换,请利用放射性同位素标记的方法,以体外培养的宿主细胞等为材料,设计实验以确定一种新病毒的类型,简要写出(1)实验思路,(2)预期实验结果及结论即 1 Subject According to the chemical composition of genetic material, the virus can be divided into two types of RNA virus and DNA virus, some viruses cause great harm to human health, usually, a new virus needs to determine the type of the virus. Assuming that there is no base-to-base conversion within the host cell, use a radioisotope-labeled method with a host cell cultured in vitro as a material to design an experiment to determine the type of a new virus and briefly (1) Experimental ideas, (2) the expected experimental results and conclusions
