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.

In eukaryotic cells, transcription cannot begin until 

• the two DNA strands have completely separated and exposed the promoter.
• several transcription factors have bound to the promoter.
• the 5' caps are removed from the mRNA.
• the DNA introns are removed from the template.
