At the acceptor end, amino acid can be attached via the 3'-OH group. At the opposite end of the molecule is the anticodon, which pairs with its complementary codon on the messenger RNA. | At the acceptor end, amino acid can be attached via the 3'-OH group.

The two arms of the "L" are formed by the <scene name='43/433638/Stemstacking/1'>stacking of the acceptor and TΨC-stem</scene>Text on one side, and of the anticodon and D-stem on the other side. <scene name='43/433638/Kissing/2'>Tertiary interactions between the TΨC- and D-loop</scene> form the corner of the L-shape and stabilise the structure. Non-Watson-Crick hydrogen bonding is important in this core. | The two arms of the "L" are formed by the <scene name='43/433638/Stemstacking/1'>stacking of the acceptor and TΨC-stem</scene>Text on one side, and of the anticodon and D-stem on the other side. <scene name='43/433638/Kissing/2'>Tertiary interactions between the TΨC- and D-loop</scene> form the corner of the L-shape and stabilise the structure.

In addition, tRNA have a variable loop located in between the acceptor and D-stems. This variable loop can be quite small, but for some tRNA such as the serine or leucine-specific tRNA, it can form an additional helix. | In addition, tRNA have a variable loop located in between the acceptor and D-stems.
