Explanation:
Detailed explanation-1: -RNAP is the multisubunit enzyme that transcribes template DNA into RNA. While bacteria (prokaryotes) and archaea contain only one RNAP, eukaryotes contain three RNAPs: RNAP I, RNAP II, and RNAP III. Though there are drastic differences between these multisubunit RNAPs, they are also many significant similarities.
Detailed explanation-2: -mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
