  • Commonly, there are stimulatory signals in mRNA distinct from the shift site that greatly increase the level of frameshifting at the shift site.2003, Jacques Lapointe, Lea Brakier-Gigras, Translation Mechanisms, →ISBN, page 354:
  • Considering these costs, it seems likely that mechanisms may exist to stop frameshifted translation as soon as possible, depending on the frequency of occurrence.2004, DNA and Cell Biology - Volume 23, page 702:
