You must try the simulation before answering the questions.
Click the promoter to simulate the RNA transcription process. You can then click on the bases in the DNA molecule to change them—each base cycles between adenine (A), guanine (G), thymine (T), and cytosine (C). Click the button again to re-run the simulation and see what your new mRNA is.
