《果蝇唾腺染色体的制备及观察》实验综述报告

该文阐述了本科院校遗传学实验课程中难度较大的《果蝇唾腺染色体的制备及观察》实验,从培养材料起,对唾腺的剥离、解离、染色、压片,再到观察唾腺染色体的实验步骤和注意事项都进行了详细的叙述。该实验对本科院校生物学专业学生具有非常重要的意义,不仅能帮助学生掌握剥离果蝇幼虫唾腺的关键技术,也使学生更直观地了解到多线染色体的形态特征和遗传学特征。

This paper describes the experiment of"preparation and observation of salivary gland chromosome of Drosophila melanogaster",which is very difficult in the course of genetics experiment in undergraduate colleges.From the point of culture materials,the experiment steps and precautions of salivary gland chromosome observation are described in detail.This experiment is of great significance to biology students of undergraduate colleges.It can not only help students master the key technology of stripping salivary gland of Drosophila larvae,but also help students understand the morphological and genetic characteristics of multiline chromosomes more directly.
