A large precursor tRNA...

I___is cleaved to produce an individual tRNA molecule.

I An intron is removed by splicing,.

and bases are added to the 3' end.

^ Modification of several bases ( • ) produces the mature tRNA.

Will form anticodon

Intron

Anticodon

Conclusion: tRNA processing may include cleavage, splicing, base addition, and base modification.
