一、困惑和质疑人教版课程标准实验教材在介绍完艾弗里的实验后,用这样一段话引入噬菌体侵染细菌的实验——“1952年,赫尔希和蔡斯以T2噬菌体为实验材料,利用放射性同位素标记的新技术,完成了另一个更具说服力的实验。”在探索遗传物质的众多经典实验中,噬菌体侵染细菌的实验真的比艾弗里的实验“更具说服力”吗?二、反思和考证1.对艾弗里的实验的再反思按照教材的描
First, puzzled and questioned the teaching standard of the people’s education curriculum experimental teaching materials After introducing Avery’s experiment, use this paragraph to introduce the experiments of bacteriophages infecting bacteria—“ In 1952, Hershey and Chase used the T2 bacteriophage as Experimental materials, using new technologies for radioisotope labeling, completed another more convincing experiment.” “In many classical experiments exploring genetic material, bacteriophage infestation experiments were really more experimental than Avery’s” More Persuasive?"
