Transcription-the synthesis of RNA using DNA as a template.
Four stages: Initiation, Elongation, Termination, Post-transcriptional modification

Similarities and Differences from Replication

Similarities                      Differences
5' →3' direction            •RNA polymerase instead
many proteins involved    of DNA polymerase
initiation, elongation,    • no proofreading termination                   • posttranscriptional
transcription bubble        modification
starts and stops at         • 1 strand copied not 2 specific places               • not all copied
                                             Nt not dNt
