snoRNA Z242 was identified in rice Oryza sativa, and is predicted to belong to the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box (UGAUGA) and the D box (CUGA).
The identification of snoRNA Z242 in rice Oryza sativa led to its classification as a member of the C/D box category of snoRNAs, which are characterized by the presence of specific sequence motifs, namely the C box (UGAUGA) and the D box (CUGA).
