WebFeb 10, 2024 · So for all three reasons, the fact that the mRNA can't enter the nucleus; the fact that the mRNA isn't DNA and would need to be translated or reverse transcribed back to DNA; and because it can't be integrated into DNA, it is not possible for messenger RNA to alter DNA. The chance of that happening is not small — it's zero. It is not possible. WebMay 14, 2024 · In all cases, however, RNA polymerase transcribes the DNA strand in its 3'→ 5' direction. A report in the 4 January 2001 issue of Nature shows that RNA polymerase actually tracks around the double helix of DNA. In vitro, at least, when RNA polymerase is immobilized, it spins the DNA molecule around and around as it moves along the molecule.
