The DNA sequence where RNA polymerase attaches is called the promoter; in prokaryotes, the sequence signaling the end of transcription is called the terminator The stretch of DNA that is transcribed is called a transcription unit

Chapter 17 (pp.315-319) – Gene expression: Transcription (continued) and Translation Learning objectives: Explain how RNA polymerase recognizes where transcription should begin. Describe the promoter, the terminator, and the transcription unit. • Explain the general process of transcription, including the three major steps of
