一激发学生思考,树立“学习是为了创造”的观念。我们在进行生物化学的教学中,“核酸代谢”这一章是个难点,也是个重点。我们在讲了核苷酸的合成代谢过程以后,根据教材内容联系到癌瘤的化疗药物如氨甲蝶呤(MTX)、5-氟尿嘧啶(5—FU)、6-巯基嘌呤(6—MP)等正是作用于嘌呤核苷酸、嘧啶核苷酸的合成代谢过程的特 A stimulating students to think, to establish “learning is to create ” concept. We are in the teaching of biochemistry, “nucleic acid metabolism,” this chapter is a difficult point, but also a focus. After we talked about the process of the synthesis and metabolism of nucleotides, we found that the chemotherapy drugs such as methotrexate (MTX), 5-fluorouracil (5-FU) and 6-mercaptopurine (6-MP) And so is the role of purine nucleotides, pyrimidine nucleotides synthesis of metabolic processes
