Best Answer: The process is called transcription. In this process, the DNA of a gene is copied into a mRNA molecule. It is not exactly copying, since it does not produce an exact DNA copy, but it makes an RNA molecule instead (which has a slightly different chemical composition). http://en.wikipedia.org/wiki/Transcripti... The enzyme that is involved in this process is called DNA dependent RNA polymerase or just RNA polymerase.
