A  tRNA molecule contains many modified bases
   and  contains a series of stems and loops, folded into a 3-dimensional
   conformation.

   The  3'  end  is the amino acid binding site, while the anticodon loop
   recognizes a codon on the mRNA.

   The anticodon (CGI) of this tRNA^ala molecule specifies the amino acid
   alanine,  and can base pair with the triplets GCU, GCC, and GCA due to
   wobble.
