题1:(2006年高考综合考试理科综合试卷<江苏卷>)以下是科学家在研究生物体的遗传和变异时做过的一些实验．根据实验分析回答: (1)实验1:检测豌豆染色体的组成成分,得到下列数据(％):DNA含36．5,RNA含9．6,蛋白质含47．9,类脂和钙等含6．0．由此可以推知组成染色体的主要成分是__和__．(2)实验2:用35S和32P分别标记噬菌体的蛋白质和DNA后,侵染未被标记的细菌,得到的子一代噬菌
Question 1: (2006 National Comprehensive Examination Exam Science Comprehensive Examination Paper ) The following are some of the experiments that scientists performed during the genetics and variation of graduate student subjects. According to the experimental analysis, the answers were as follows: (1) Experiment 1: The composition of pea chromosomes was examined and the following data (%) were obtained: DNA contained 36.5, RNA contained 9.6, protein contained 47.9, lipid and calcium contained 6 .0. It can be inferred that the main components of the constituent chromosomes are __ and __. (2) Experiment 2: Infection with unlabeled bacteria after labeling of phage proteins and DNA with 35S and 32P, respectively
