Processing of a pre-tRNA.
A typical pre-tRNA undergoing processing steps to generate a mature tRNA ready to have its cognate amino acid attached. Nucleotides that are cleaved away are shown in green. Chemically-modified nucleotides are in yellow, as is the CAA trinucleotide that is added to the 3' end of the pre-tRNA during processing. The anticodon nucleotides are shown in a lighter shade of red.
