1 Prokaryotic Transcription Eukaryotic Transcription Both

2 Prokaryotic Transcription Eukaryotic Transcription Both Follow the stages of: 1)Initiation 2)Elongation 3)Termination

3 Prokaryotic Transcription Eukaryotic Transcription Both Follow the stages of: 1)Initiation 2)Elongation 3)Termination Require recognition of a promoter on DNA by RNA polymerase enzyme

4 Prokaryotic Transcription Eukaryotic Transcription Both Follow the stages of: 1)Initiation 2)Elongation 3)Termination Require recognition of a promoter on DNA by RNA polymerase enzyme Synthesize RNA in 5’  3’ direction, using DNA as a template

5 Prokaryotic Transcription Eukaryotic Transcription Both Follow the stages of: 1)Initiation 2)Elongation 3)Termination Require recognition of a promoter on DNA by RNA polymerase enzyme Synthesize RNA in 5’  3’ direction, using DNA as a template Initiation requires no transcription factors – RNA polymerase binds directly to promoter Initiation requires transcription factors – RNA polymerase cannot bind directly to promoter

6 Prokaryotic Transcription Eukaryotic Transcription Both Follow the stages of: 1)Initiation 2)Elongation 3)Termination Require recognition of a promoter on DNA by RNA polymerase enzyme Synthesize RNA in 5’  3’ direction, using DNA as a template Initiation requires no transcription factors – RNA polymerase binds directly to promoter RNA transcript produced from transcription is the final mRNA, requiring no further processing/modifica tion Initiation requires transcription factors – RNA polymerase cannot bind directly to promoter RNA transcript produced from transcription is not the final mRNA; rather, it is a pre- mRNA that requires further processing/modifica tion

7 Prokaryotic Transcription Eukaryotic Transcription Both Initiation requires no transcription factors – RNA polymerase binds directly to promoter RNA transcript produced from transcription is the final mRNA, requiring no further processing/modifica tion Takes place in the cytoplasm Follow the stages of: 1)Initiation 2)Elongation 3)Termination Require recognition of a promoter on DNA by RNA polymerase enzyme Synthesize RNA in 5’  3’ direction, using DNA as a template Initiation requires transcription factors – RNA polymerase cannot bind directly to promoter RNA transcript produced from transcription is not the final mRNA; rather, it is a pre- mRNA that requires further processing/modifica tion Takes place in the nucleus
