The rRNA is Rybosomal RNA, its the one from which the Rybosomes are made of. The RNA Polymerase is the enzyme in charged of the RNA Transcription, it depends on certain Initiation Factors, the Promotor (usually TATA box) to start it. So rRNA gives the "form" to the Rybosomes found in the Cytoplasm or attached to the RER The RNA Polymerase is an enzyme and it is found inside the Nuclus

What is the difference between mrna trna and rrna?
These are all terms for types of RNA, or ribonucleic acid. The difference is that mRNA is messenger RNA, tRNA is transfer RNA, and rRNA is ribosomal RNA.
How many RNA polymerase does bacteria have?
Three. pol1 pol2 and pol3. pol 3 is mostly used and 2and 1 are used for proofreadingonly one. rna polymerase^^^ The above answer is wrong. Bacteria only has 1 RNA polymerase, while a Eukaryote has 3 RNA polymerase. RNA Polymerase 2 transcribes structural genes (responsible for synthesis of mRNA), RNA Polymerase 1 transcribes all rRNA genes (except the 5s rRNA- a component of one of the ribosome subunits). RNA polymerase 3 transcribes all tRNA + the 5s rRNA.
Are all three types of RNA coded by the same genes?
There are different types of genes for encoding three types of RNA. Protein coding genes are transcribed by RNA polymerase II to yield mRNA. Ribosomal RNA (rRNA) are transcribed by RNA polymerase I. Likewise, transfer RNA (tRNA) are transcribed by polymerase III.
What is RNA polymerase?
The RNA polymerases are huge multi-subunit protein complexes. Three kinds are found in eukaryotes: * RNA polymerase I (Pol I).It transcribes the rRNA genes for the precursor of the 28S, 18S, and 5.8S molecules (and is the busiest of the RNA polymerases). * RNA polymerase II (Pol II; also known as RNAP II).It transcribes protein-encoding genes into mRNA (and also the snRNA genes). * RNA polymerase III (Pol III).It transcribes the 5S rRNA genes and all the tRNAgenes.

Where does RNA polymerase bind?
RNA polymerase is the enzyme responsible for the synthesis of RNA molecules from DNA in a process called transcription. It adds RNA nucleotides in the 5’ to 3’ direction to produce the single-stranded RNA molecule. This RNA can be either messenger RNA (mRNA), transfer RNA (tRNA) or ribosomal RNA (rRNA). All three types of RNA are involved in the protein synthesis. The binding of the RNA polymerase requires the identification of the promoter of the gene, which is going to be transcribed. Upon binding of the enzyme, RNA polymerase adds complementary RNA nucleotides to the antisense strand of DNA

I believe that it comes from polymerase I, which localizes in the nucleolus, and synthesizes rRNA. The multiple eukaryotic RNA polymerasis apparently originated through duplication of primordial subunit genes, followed by evolution of specialized functions.

What is RNA produced by?
Ribosomal RNA (rRNA) production represents the most active transcription in the cell. Synthesis of the large rRNA precursors (35-47S) can be achieved by up to 150 RNA polymerase I (Pol I) enzymes simultaneously transcribing each rRNA gene. In this paper, we present recent advances made in understanding the regulatory mechanisms that control elongation. Built-in Pol I elongation factors, such as Rpa34/Rpa49 in budding yeast and PAF53/CAST in humans, are instrumental to the extremely high rate of rRNA production per gene. rRNA elongation mechanisms are intrinsically linked to chromatin structure and to the higher-order organization of the rRNA genes (rDNA). Factors such as Hmo1 in yeast and UBF1 in humans are key players in rDNA chromatin structure in vivo. Finally, elongation factors known to regulate messengers RNA production by RNA polymerase II are also involved in rRNA production and work cooperatively with Rpa49 in vivo.
