GO:0006425:   glutaminyl-tRNA aminoacylation
The process of coupling glutamine to glutaminyl-tRNA, catalyzed by glutaminyl-tRNA synthetase. The glutaminyl-tRNA synthetase is a class-I synthetase. The activated amino acid is transferred to the 2"-OH group of a glutamine-accetping tRNA. The 2"-O-aminoacyl-tRNA will ultimately migrate to the 3" position via transesterification.
