t-RNA and r-RNA need splicing or not?

Hi,
tRNA(also tRNA-like) splicing is another rare form of splicing that usually occurs in tRNA. The splicing reaction involves a different biochemistry than the spliceosomal and self-splicing pathways.
Alsopre-rRNA cannot be used forprotein production until splicing of the introns occurs, forming a new bond between the exons and resulting in mature ribosomal RNA (rRNA)
