Question
What is used to signal termination in transcription
Solution
In transcription, termination signals are used to indicate where the process should stop. In bacteria, this is often a specific sequence of DNA bases that forms a "hairpin" structure in the RNA transcript, causing the RNA polymerase to detach from the DNA and release the RNA transcript. In eukaryotes, the process is a bit more complex and often involves a specific sequence of DNA bases that signals a set of proteins to come in and cut the RNA transcript free from the RNA polymerase.
