Ribosomal RNA or rRNA and transfer RNA or tRNA are the gene products that are RNA.
Explanation:
The ribonucleic acid of the ribosomes is a non-coding RNA. It is a part of ribosomes where protein synthesis takes place. Ribosomal DNA gets transcribed into ribosomal RNA. The gene clusters code for rRNA. In rRNA transcription is performed RNA Polymerase 1 enzyme. There are subunits in rRNA which are synthesized separately and assembled.
Transfer RNA molecule is also transcribed but does not undergo translation as it itself has a role in translation. In translation, it brings the particular amino acid that is coded by mRNA to the growing polypeptide chain of amino acids. It is transcribed by tRNA gene and undergoes posttranscriptional modification.
