Polyadenylation Signal
Also written as AAUAAA.
Transcription ends when RNA polymerase II reaches a termination signal — this is a special sequence in the RNA: AAUAAA (called the polyadenylation signal).
What our notes say
- Transcription ends when RNA polymerase II reaches a termination signal — this is a special sequence in the RNA: AAUAAA (called the polyadenylation signal). (🔹 Eukaryotic Transcription & Translation)
- Includes a polyadenylation signal (AAUAAA) that leads to mRNA cleavage and polyadenylation. (Transcription Factors)
- Termination requires polyadenylation signals (AAUAAA sequence). (Transcription Factors)
