Summarize the steps of transcription. Pre-mRNA is made from the templar strand of DNA starting at the promoter by the transcription initiation complex. When the RNA polymerase reaches the terminator, the pre-mRNA is released. Introns are removed and the methyl cap and poly-A tail are added to make mRNA.
