        Another type of RNA called
        transfer RNA (tRNA) carries                                                              A  A  G
        specific amino acids.
                                                                                               anticodon
        Every tRNA has an anticodon
        region that is complementary to a       U A U U    U C  G C  G A A   G C   U A U   A U   U U C
                                             A
        specific codon on the mRNA.
