Best Answer: Transcription. DNA---Transcription---mRNA---Translatio... In transcription DNA is unzipped and the enzyme RNA polymerase runs along the template strand of the DNA. The template strand of DNA can be identified by finding the nucleotide sequence T A C at the 3â end (you can see this on your template strand).RNA, or messenger RNA, is generated by reading a strand of DNA. RNA polymerase (an enzyme that specifically makes mRNA) moves along the strand of DNA and joins complementary strands (in RNA, the complement to adenine is uracil instead of thymine). mRNA is produced only for the gene that is being read at that time.
