Transmission of genetic information

　　Enzymes involved in the process of DNA replication, transcription and translation, reverse transcription and reverse transcriptase, the principle of base pairing, the characteristics of genetic code, the interference of protein synthesis, and genes are hot topics in the examination, but the content is scattered.Therefore, we should understand small molecules Many benefits, absorb and summarize, and use them. https://www.all-chemistry.com/

　　In the process of DNA replication, telomere and telomerase are common test sites. Telomerase is an enzyme composed of RNA and protein. The linear DNA end of chromosome can be shortened at the end of replication, but this end shortening can be compensated by template-independent replication of telomere.

　　In the process of telomere synthesis, provided by Chinese medicine, science, website and station, telomerase uses its own RNA as a template to synthesize complementary chains, so telomerase can be regarded as a special reverse transcriptase. Reverse transcription and reverse transcriptase. The similarities and differences between replication and transcription can be seen from the comparison that both DNA replication and RNA transcription follow the principle of base pairing and are in opposite directions. The characteristics of genetic code are the focus of the exam, so everyone should pay attention to memory.
