Each of the 3 RNA polymerase in eukaryotes perform a different function. For example, RNA pol 2 is involved in mRNA synthesis, RNA pol 1 synthesizes most rRNAs and RNA pol 3 synthesizes tRNNA, the 5S rRNA and other small nuclear RNAS. Eukaryotes are more complex than prokaryotes, hence why eukaryotes would require more RNA polymerases.

What are the different types of RNA polymerases and their promoters?
rma polymerase 1, rna polymerase 2, rna polymerase 3
What is produced in transcription?
Transcription in Prokaryotes requires one enzyme for the 4 stages of: 1) binding of RNA polymerase holoenzyme at promoter sites, 2) initiation of polymerization, 3) chain elongation, and 4) chain termination Transcription in Eukaryotes requires three RNA polymerases I, II, and III transcribe rRNA, mRNA, and tRNA genes respectively.
In which direction does RNA polymerase read a DNA strand?
The correct answer is: RNA is synthesized by RNA polymerase that reads one strand of DNA. RNA polymerase reads DNA 3' to 5'. When RNA is made, it is made 5' to 3'. Most polymerases have the 3' to 5' "reading" activity. The created RNA strand is identical to the coding strand of DNA, which is also in the orientation of 5' to 3'.
What direction does RNA polymerase move along the DNA?
Nucleotides are being added as RNA polymerase moves along the DNA template strand.
RNA polymerase moves in which direction along the DNA?
3'-5' along the template strand

Where does the RNA polymerase moves down?
RNA polymerase catalyze the synthesis of RNA by copying the DNA. It occurs in the 5' to 3' direction(moves down).

What direction does RNA polymerase move along the DNA?
Nucleotides are being added as RNA polymerase moves along the DNA template strand.
What are the similarities between rna polymerase and DNA polymerase?
Both RNA and DNA form in the same manner. They add bases to the 3' end of the base to form a polymer.
What enzyme attaches RNA nucleotides the the exposed 3' end of a growing mRNA transcript?
RNA Polymerase
What are the similarities between DNA polymerase and RNA polymerase?
Both RNA and DNA form in the same manner. They add bases to the 3' end of the base to form a polymer.
What is RNA polymerase and what is its job?
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.
RNA polymerase moves in which direction along the DNA?
3'-5' along the template strand
Why does RNA polymerase work in direction 5' to 3' not from 3' to 5'?
Any polymerase (DNA or RNA) works in the 5`-3` direction (downstream) because the 3` end contains the hydroxyl groups. The 5` phosphate binds covalently with the 3` hydroxyl group forming a phospho diester linkage.
