[Splicing. I. Splicing of tRNA, rRNA and mRNA in organelles].
Mosaic structure of genes is shown for three out of four known types of RNA: transfer, ribosomal and messenger. At least three different mechanisms are involved in maturation of transcripts from these genes. The peculiarity of tRNA splicing is connected with the possibility of existence of tRNA molecules free of ribonucleoprotein complexes. The mode of Tetrahymena pre-tRNA self-splicing may also take place during maturation of other RNAs (rRNA of protozoa, ribosomal and messenger rRNA of lower fungi, plant messenger rRNA), which share the similar structure. The third type of mechanism is involved in splicing messenger RNA in eukaryotic cell nuclei.
