'''Transcription''' is the biological process by which [[prokaryotic]] and [[eukaryotic]] cells generate single stranded [[RNA]]  

through the enzymatic action of a specific isoform of [[RNA polymerase]]. It is the intermediary step in the production of [[proteins]], and the final step for non-protein coding RNAs. Protein coding genes are transcribed into mRNA which is then translated by the [[ribosome]] to create a nascent [[polypetide]] chain.

Non-protein coding RNAs are transcribed from [[DNA]] for the production of ribosomal RNA, transfer RNA, and small nuclear RNAs which serve various other functions in the cell. The biochemical process is similar to DNA replication in that it requires the action of multiple enzymes to unravel double-stranded genomic DNA which allows an enzyme ([[DNA polymerase]]) to processively catalyze the formation of an anti-sense strand based on proper nucleotide base pairing.
