During gene transcription, an RNA molecule is produced by copying the DNA sequence of a gene. This RNA molecule can be further processed into messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), or other types of functional RNA molecules that carry out various cellular functions.
Ribosomal RNA (rRNA) is produced in the nucleolus of the cell by RNA polymerase I. The nucleolus is a specialized structure within the nucleus that is responsible for synthesizing rRNA and assembling ribosomes.
Messenger RNA (mRNA) is synthesized during transcription in the nucleus before transfer RNA (tRNA) comes into play during translation in the cytoplasm. So, mRNA is produced first in the sequence of events.
RNA is synthesized by an enzyme called RNA polymerase. This enzyme catalyzes the process of transcription in which RNA is produced from a DNA template. RNA polymerase adds nucleotides to the growing RNA strand according to the complementary base pairing rules.
Maximum formation of RNA occurs in the nucleus of eukaryotic cells, where transcription takes place. RNA is produced from DNA templates by the enzyme RNA polymerase, and the nucleus provides a controlled environment for this process to occur efficiently.
Ribosomal RNA is produced from the nucleolus.Ribosomal RNA consists of rRNA and protein.There are three types of RNA's in our body: mRNA, rRNA and tRNA.

Unmodified RNA is produced through transcription. Where transcription occurs depends on if the organism is a prokaryote (bacteria or archea) or eukaryote (plant or animal). RNA in prokaryotes is produced inside the cell membrane. RNA in eukaryotes is produced inside the nucleus.
RNA is read off of the DNA located in every cell.
The dense region in the nucleus where ribosomal RNA is produced is called the nucleolus. Ribosomal RNA is also coupled with specific proteins within the nucleolus.
The dark region of chromatin where RNA is produced is called the nucleolus. It is primarily responsible for producing ribosomal RNA (rRNA) and ribosomes, which are essential for protein synthesis within the cell.
