This side of the tRNA molecule contains structural features likely to be common for all tRNAs. Depending on the system, an enzyme may span a small part or all of the region of this side of the molecule. Interactions with other parts of the structure may also occur in a manner that varies from complex to complex.

How would you describe the structure of a tRNA? - Quora Answer (1 of 4): The structure of tRNA can be decomposed into its primary structure, its secondary structure (usually visualized as the cloverleaf structure), and its tertiary structure (all tRNAs have a similar L-shaped 3D structure that allows them to fit into the P and A sites of the ribosome)... A Conformational Study of Yeast Phenylalanine Transfer Ribonucleic Acid Phenylalanine tRNA's from yeast (20, 21), wheat germ (21, 22), bovine liver (21), and rat liver (23) each contain a strongly fluorescent base of unknown structure. In tRNAPhe 1 from yeast (20) and wheat germ (22) this modified base is located next to the 3' end of the anticodon sequence; presumably it occurs in the ...

Transfer RNA - Wikipedia The tRNA structure consists of the following: A 5′-terminal phosphate group. The acceptor stem is a 7- to 9-base pair (bp) stem made by the base pairing of the 5′-terminal nucleotide with the 3′-terminal nucleotide (which contains the CCA 3′-terminal group used to attach the amino acid).

On the Structure of Phenylalanine tRNA from Yeast 2-Thiocytidine incorporated into tRNA Phe from yeast by tRNA nucleotidyl transferase can be alkylated by iodoacetamide and its derivatives. Using this method a spin label was introduced specifically into tRNA Phe and the product, tRNA Phe -C- (s.l.)s 2 C-A, can still be aminoacylated by phenylalanyl-tRNA synthetase.
