The anticodon is the signal sequence for mitochondrial import of glutamine tRNA in Tetrahymena.

Abstract excerpt

The import of nuclear-encoded RNAs into mitochondria is required for proper mitochondrial function in most organisms. However, the mechanisms used to achieve RNA import are largely unknown. In particular, the RNA elements that direct import have not been identified in any organism. In Tetrahymena, only one of three nuclear-encoded glutamine accepting tRNAs is imported into mitochondria. We transform Tetrahymena...
