<span>Initiation is when the RNA polymerase separates the strands of DNA at the site of the promoter and connects the RNA nucleotides while they base pair with the DNA template. Elongation is when the polymerase moves downward undoing the DNA and stretching the RNA transcript to the 3 prime end. As this occurs the strand begins to form a double helix. Termination is when the RNA transcript is released and the polymerase disconnects from the DNA.</span>
