A characteristic shared by eukaryotic mrna, trna, and ribosomal rna is that

Transcription is from DNA

mRNA is a template that serve as a temporary copies of the information that is found in DNA while rRNA is a structural components of ribosome which is a protein making structure and tRNA transfered amino acid to the ribosome to be assembled. However, characteristic shared by eukaryotic mrna, trna, and ribosomal rna is that they are all transcribed from DNA.
