According to his experience as a high school biology teacher for many years, he specially sorted out the difficult points that high school students need to break through in biology learning: (The following college entrance examination question types are mainly based on the Liaoning Provincial College Entrance Examination Papers)
3. Mitosis and meiosis
This part of the content mainly examines the student's understanding of the splitting process, the two splitting process diagrams are often put together for examination, students are easy to confuse, so it is important to understand the dynamic process of these two splitting methods, and it is necessary to memorize the dynamics of the graphics in order to better analyze related problems. In addition to the understanding of dynamic processes, this part of the content is often combined with genes, genetic calculations and other content, which greatly increases the difficulty of examination, and it is important to establish a good relationship between genes, DNA and chromosomes!
4. Dna replication and gene expression
The knowledge points of this part of the content are relatively easy to understand, but it is still necessary to memorize the basic points and processes of DNA replication, transcription and translation, and then learn to analyze the process of RNA replication and reverse transcription. Although this part of the content knowledge point is relatively simple, but when answering the question, students are easy to make mistakes, which is also because this part of the knowledge point is often examined in the form of material information questions, etc., when it comes to some new terms or some current events hot organisms, students are easy to get started, which requires the analysis of the test question information on the basis of understanding knowledge, in fact, it is inseparable.
I am Yu Dan, a biology teacher in the college entrance examination, and I use easy-to-understand language to talk about the biology knowledge of the college entrance examination. Follow me, or discuss with me, gaokao kids, come on!
