What does your textbook say about 5.11. tRNA – the adapter molecule?
The transfer RNA, (tRNA) molecule of a cell acts as a vehicle that picks up the amino acids scattered through the cytoplasm and also reads specific codes of mRNA molecules. Hence it is called an adapter molecule. This term was postulated by Francis Crick. The two dimensional clover leaf model of tRNA was proposed by Robert Holley. The secondary structure of tRNA depicted in Fig. . looks like a clover leaf . In actual structure, the tRNA is a compact molecule which looks like an inverted L . The clover leaf model of tRNA shows the presence of three arms namely DHU arm, middle arm and TΨC arm.
