GO:0070145:   mitochondrial asparaginyl-tRNA aminoacylation
The process of coupling asparagine to asparaginyl-tRNA in a mitochondrion, catalyzed by asparaginyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2"- or the 3"-hydroxyl group of the 3"-adenosine residue of the tRNA.
