Translation is the process by which genetic information is converted into proteins, the workhorses of the cell. Small molecules called transfer RNAs (tRNAs) play a crucial role in translation; they are the adapter molecules that match codons (the building blocks of genetic information) with amino acids (the building blocks of proteins). Organisms carry many types of tRNAs, each encoded by one or more genes (the tRNA gene set).
