«In this scenario, a smaller virus infected different eukaryote hosts and picked up genes encoding translational machinery components from independent sources over long periods of time through piecemeal acquisition,» she said. (sciencedaily.com)
This increased protein synthesis, or translation, can be traced back to elevated expression levels of RNA polymerase I, a macromolecular assembly that produces a major component of the translational machinery. (systemsbiology.org)
