Transfer RNAs are ~75 bp, so.... no.

Yes, but the OP says his ssRNA ladder ran fine, which argues against 
degradation in the gel.

To the OP - are you sure what size ribosomal bands you're expecting from 
Paramecium?  I strongly doubt it'll be the exact same pattern/size you'd 
expect from mammalian cells.
