1. Transcription versus Replication
a. Given that RNA polymerase does not proofread, do you expect high or low levels of error in transcription as compared with DNA replication?
b. What is the significance of this difference?
2. What are the transcription start and stop signals in eukaryotes and prokaryotes?
