RNA polymerase structure

RNA polymerase is a complex enzyme responsible for copying DNA into RNA. Its structure includes a central core made up of multiple protein subunits that work together like a sophisticated machine. This core has a "pocket" where the DNA binds, and a channel through which the newly formed RNA strand exits. It also has specialized regions that recognize specific DNA sequences and catalyze the addition of RNA nucleotides. Overall, RNA polymerase is a finely tuned molecular assembly that ensures accurate transcription of genetic information from DNA to RNA.
