Expression data from polysomal, nonpolysomal, and total RNAs in the S. cerevisiae tRNA trafficking mutants, msn5 and mtr10

tRNAs are transcribed and partially processed in the nucleus before they are exported to the cytoplasm where they have an essential role in protein synthesis转运RNA（transfer RNAs，tRNAs）会在细胞核内完成转录与部分加工过程，随后被转运至细胞质中，并在蛋白质合成过程中发挥至关重要的作用。
