Forms of RNA and their importance in the evolution of cellular life on Earth

1. Ribozymes and Riboswitchess

2. Transfer RNAs/ tRNA Type I and Type II

3. Ribosomal RNAs

4. Spliceosome snRNAs (modify pre-mRNA )

5. Trans-Splicing SL RNA

6. snoRNAs (chaperone and modify rRNA)

7. miRNAs (mirtrons), piRNAs, miRNA's non-intronic/POL II, III dependent, pre-miRNA

8 siRNAs

9. pre-messenger RNAs --------->mRNAs capped and uncapped

10. tmRNAs

11. RNAse P RNAs (modify tRNA and rRNA)

12. RNAse MRP/RNA dependent RNA Polymerase/RMRP (modify small subunit rRNA, mRNA for cyclin B protein, manufacture siRNA )

12. Telomerase RNA

13. vault RNA

14 SRP RNA

15. Viral RNA single positive stranded

16. Viral RNA single negative Stranded

17. Double Stranded viral RNA

18. Pre-pseudogene RNA

19. XIST RNA (X chromosome inactivating RNA )
