Question: what would be the anticodon for a trna that transports phenylalanine to a ribosome?
Answer: Each type of tRNA has a specific anticodon that is complementary to one codon of the genetic code. For example, if you have the codon for phenylalanine on the mRNA (UUU), the tRNA that carries phenylalanine will have the anticodon (AAA), the complement of UUU(see figure below).
