The right answer is transcription.
Transcription is a biological mechanism for the synthesis of an RNA molecule from a complementary DNA molecule. This is the first step in the process of moving from DNA to protein. Transcription is catalyzed by an enzyme: RNA polymerase.
In prokaryotes, transcription takes place in the cytosol, and in eukaryotes, transcription takes place in the nucleus.
Eukaryotes possess three RNA polymerases, RNA polymerase II being the one that is at the origin of mRNAs (messenger RNAs).
