The function of transfer RNA during protein synthesis is to
- A. carry the genetic message out of the nucleus
- B. form the structural core of the ribosome
- C. unwind the DNA double helix
- D. bring the correct amino acid to the ribosome according to the codon being read
Explanation
Each tRNA carries an anticodon at one end and its matching amino acid at the other, so it acts as the adaptor that translates the language of bases into the language of amino acids. Messenger RNA is the molecule that carries the message from the nucleus, and ribosomal RNA forms the structure of the ribosome, so all three types work together. Unwinding DNA is the job of helicase.
