Which of the following statements concerning transfer RNA is true?
A) It has the highest molecular weight of the commonly occurring forms of RNA.
B) It has no internal hydrogen bonding.
C) It bonds to amino acids in the course of protein synthesis.
D) All of these are true.

Question

Quizplus · Accepted Answer

Transfer RNA (tRNA) bonds to amino acids during protein synthesis, guiding them to the ribosome where they are assembled into a polypeptide chain. tRNA is also known for its unique internal structure, which is stabilized by intramolecular hydrogen bonding. It has a lower molecular weight than messenger RNA (mRNA) or ribosomal RNA (rRNA). Therefore, statement A is false, and B is also false because tRNA does have internal hydrogen bonding.
