tRNA Structure and the Anticodon
Captions available
The idea
A transfer RNA carries one specific amino acid at one end and displays a three-nucleotide anticodon at the other, pairing with a complementary codon.
In practice
A tRNA with anticodon AAG pairs with codon UUC and carries the amino acid phenylalanine to the ribosome.
Where people slip
A tRNA's anticodon pairs with an mRNA codon, not a DNA sequence — tRNA never interacts with DNA directly.
