细胞核是遗传信息（The nucleus is genetic information） The nucleus is the library of genetic information Jiangxi province Jingdezhen City Changhe middle school: Li Andai I. the status of teaching materials: This textbook is taught standard biological experimental textbook version of compulsory education curriculum grade seven second unit second chapter second section. The second chapter contains three sections. The first section tells of the need for energy in cell life, which describes the functions of the two basic structures of the cell membrane and cytoplasm. As an important part of the second chapter of cell life, this textbook explains the important function of the nucleus -- genetic information database. This constitutes a complete knowledge of the basic cell structure and function, but also laid the foundation for the next day to learn and understand the knowledge of cell division, cell life to enable students to have a basic understanding. Two, teaching objectives 1, knowledge objectives (1) describe the scientific and technological process of the birth of cloned sheep and come to the conclusion that there is genetic material in the nucleus. (2) the relation between chromosome, DNA and genetic information. (3) the nucleus is a genetic information library. 2, ability target: Through the collection of relevant biological information before class, we will learn to collect and process information. By cloning sheep, DNA is genetic material analysis, so as to improve the ability to collect and process information, to improve thinking ability, analysis and problem-solving ability, language expression ability. Train students Dialectical views through debate and other activities. 3, emotions, attitudes, values, goals: Cultivate the spirit of exploration to explore the mysteries of life. Understanding DNA is the material basis of heredity, experiencing the scientific attitude of seeking truth from facts; paying attention to social hot topics, so as to enhance students sense of
