This polymerase contains four catalytic subunits ... For example, researchers know that RNA pol II can bind to a DNA sequence within the promoter of many genes, known as the TATA box, to initiate ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries ... types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is ...

DNA polymerase enzymes facilitate this process, ensuring accurate copying of the genetic information. Transcription is the process by which the genetic information in DNA is copied into a ...
