The genetic code is essentially the same for all organisms. From this, one can logically assume which of the following?

The anticodon of a particular tRNA molecule is 

• complementary to the corresponding mRNA codon.
• complementary to the corresponding triplet in rRNA.
• the part of tRNA that bonds with a specific amino acid.
• catalytic, making the tRNA a ribozyme.
