This movement protects the genetic transcripts from the recruitment of "spliceosomes".
Researchers at the University of Göttingen and the University Medicine Centre Göttingen have demonstrated the underlying mechanism in the cell.
The results were published in the journal Cell Reports.
Human cells are made up of the following: a cell nucleus, which contains the genetic material in the form of DNA; and the cytoplasm, where proteins are built.
Separated from the original transcript, the proteins can then be produced in the cytoplasm.
The separation is important because the messenger RNA is not immediately usable; rather, a precursor (pre-messenger RNA) has to be produced that still contains areas that have to be removed before the messenger RNA reaches the cytoplasm.
