Which RNA polymerase makes rRNA?

Posted October 25, 2021


RNA polymerase I makes rRNA. RNA polymerase I is found only in the nucleolus of eukaryotes, a specialized nuclear substructure where ribosomes are assembled. RNA polymerase synthesizes ribosomal RNA (rRNA) transcripts in the nucleolus. These transcripts are directly involved with the production of ribosomes.
