第二单元第二章第二节细胞核是遗传信息库（The second unit, the second chapter, the second section, the nucleus is the genetic information database） The second unit, the second chapter, the second section, the nucleus is the genetic information database Knowledge and skills Human life begins with a ____, with all the information to guide the physical development in its ____, called ____. Carrier of genetic information in the nucleus is a kind of organic matter called ____, it can be divided into many segments, each segment has a specific ____, these fragments called ____. The chromosome is the nucleus can be ____ dyed with dark matter, which is composed of the two elements and ____. Every kind of biological cells, chromosome number is certain, ____ normal life and this is very important on. Reference answer: The zygote nucleus genetic information DNA gene DNA protein basic genetic information reproduction Process and method 1. describe the important function of the nucleus in biological inheritance -- the genetic information library, which tells the relationship between chromosomes, DNA and genetic information. 2., for example, biological traits are controlled by genes. 3. students through data analysis and Simulation of production activities, to clarify the genetic information stored in the nucleus, so as to cultivate the ability of collecting and processing information, improve the thinking ability and the ability to analyze and solve problems, language expression ability and the ability of making simulation. Emotion, attitude and values Through simulation activities, students can improve their practical ability and cultivate their cooperative spirit. In the course of learning this lesson, students will feel the emotion of life. Cooperate with you to explore 1. explore the relationship between chromosomes, DNA, genes How genetic information is carried by genetic material? The gene should be a specific section of DNA! The chromosome exists in the nucleus and has a certain number, which i
