Question

Where is RNA polymerase located?

Answer 1

RNA polymerase:

The nucleus, as well as mitochondria and chloroplast, contain RNA polymerase.

1. The nucleolus is a specialized nuclear substructure that contains RNA polymerase I, which is in charge of ribosomal RNA (rRNA) transcription, processing, and assembly into ribosomes.
2. RNA molecules are categorized as structural RNAs because they have a biological function but are not translated into protein.
3. The nucleolus contains RNA polymerase.
4. RNA polymerase I is made up of 14 subunits.
5. Three nuclear enzymes, RNA polymerase I, II, and III, are used in eukaryotes to produce different classes of RNA as opposed to prokaryotes, which have a single RNA polymerase that transcribes all types of RNA.
6. Polymerase I promoter sequences change widely across species.
