Transcription of RNA from DNA
In this
diagram, RNA synthesis has already been proceeding
for some time: the dsDNA at the left was opened,
transcribed, and then re-closed.The RNAPol molecule
opens the dsDNA, the RNA molecule is
synthesized in the 5'3' direction, off of
the template DNA strand. The
5' end is transcribed first, and afterwards is
unchanged.
