Exam 3 Answer Key – Discovery and Innovation – The correct answer is a. They have an anticodon at their 5′ end and an amino acid attachment site at their 3′ end. Diagram showing the structure of tRNA, the anticodon is indicated by CAU at the end of the one loop (Yikrazuul [CC BY-SA 3.0 (https://creativecommons.org/licenses/by-sa/3.0)])Which of the following statements about tRNA molecules is false? A) A, C, G, and U are the only bases present in the molecule. B) Although composed of a single strand of RNA, each molecule contains several short, double-helical regions. C) Any given tRNA will accept only one specific amino acid.tRNAs associate with sites on the ribosome in the order listed. 10 When a peptide bond is formed between two amino acids, one is attached to the tRNA occupying the P site and the other _______.
