Polymerases are the enzymes that replicate and build nucleic acids. DNA polymerases synthesize DNA, RNA polymerases synthesize RNA. Purified polymerases are essential to carrying out the PCR reaction.
RNA and DNA polymerases are enzymes and hence, they are proteins.
RNA molecules are synthesized by enzymes known as RNA POLYMERASES .http://www.answers.com/topic/rna-polymerasehttp://www.answers.com/topic/rna-polymerase
RNA polymerase bind specific regions of DNA called promoters. The RNA polymerase holoenzyme is guided to promoters by interactions between members of the holoenyzme and specific DNA sequences such as the TATA box.
They are completely different processes in the central dogma. DNA replication is the replication of DNA into DNA by DNA polymerases. Trancription is the transcription of DNA into RNA by RNA polymerase.

RNA polymerases
Polymerases are the enzymes that replicate and build nucleic acids. DNA polymerases synthesize DNA, RNA polymerases synthesize RNA. Purified polymerases are essential to carrying out the PCR reaction.
Molecular biologists have found that certain DNA sequences serve as promoters, bindings sites for RNA polymerases serve as starts and stops signals for transcription.

RNA and DNA polymerases are enzymes and hence, they are proteins.
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.

An RNA virus whose genome is complementary to RNA and that carries mRNA polymerases necessary for the synthesis of a new virus.
They are completely different processes in the central dogma. DNA replication is the replication of DNA into DNA by DNA polymerases. Trancription is the transcription of DNA into RNA by RNA polymerase.
