What does transcription do

The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases. Elongation is the addition of nucleotides to the mRNA strand. Termination is the ending of transcription, and occurs when RNA polymerase crosses a stop termination sequence in the gene. This video provides a review of these steps.

Inverted repeat sequences at the end of a gene allow folding of the newly transcribed RNA sequence into a hairpin loop. This terminates transcription and stimulates release of the mRNA strand from the transcription machinery.
