What are the functions of RNA polymerase? This is what many people want to know comprehensively, because many people now pay special attention to health, and want to make their bodies healthy and improve the quality of life, so they want to have a comprehensive understanding of this aspect. The following content introduces this aspect in detail. If you want to have a comprehensive understanding, you can read the introduction below. According to relevant literature, there is only one type of RNA polymerase in prokaryotic cells, which is responsible for checking three types of RNA. One factor in the RNA enzyme has the ability to recognize the promoter "recognition site" and bind to it to form a loose complex. The RNA polymerase then moves along the 3"-5" direction of the template DNA to the Pribnow box, an area that is easily unwound. There are three types of RNA polymerases in eukaryotic cells. The one that can synthesize mRNA is RNA polymerase II. Different RNA polymerases have different promoters, which are more complex and diverse than prokaryotic cell promoters. Prokaryotic cells rely on RNA polymerase itself to recognize promoters, while eukaryotic cells' RNA polymerase cannot recognize promoters and must rely on transcription factors to do so. There are six main types of transcription factors, each with different functions. Transcription factors bind to the TATA box on the template DNA to form a transcription initiation complex, which is a multi-subunit protein complex with DNA helicase activity that depends on ATP energy supply and plays a role in transcription chain elongation. In short, in the process of genetic information transcription, RNA polymerase plays an unwinding role in prokaryotic cells, while certain transcription factors play an unwinding role in eukaryotic cells. Therefore, in the process of genetic information transcription, helicase is not involved. Helicase is only needed in the process of DNA replication. What are the functions of RNA polymerase? I believe that through the above introduction, you have a comprehensive understanding of this aspect. RNA polymerase has many functions, and because of its participation, you can reduce the risk of disease. And if someone gets this disease, thanks to his participation and role, they can recover through treatment as quickly as possible. |
