Assertion: codon's trna | /r/HasAspect | similar l-shaped 3d structure
Facets:
Source sentences:
text: 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).
