2. in multcellular eukaryotes, the play an essential role in initiating the formation of the commitment complex
4. The group introns with ability to excercise themselves
6. occurs when a single gene gives rise to more than one mRNA sequence
10. 70 proteins found in the spliceosomes
12. have a structure resembling the Sm-binding site of U-snRNAs
14. the commitment complex is also called
17. heterogeneous nucleur RNA
19. are the sequences that are represented in the mature proteins in rna splicing
20. depends only on recognition of splice sites
22. RNA involved in processing ribosomal RNA

1. occurs in trypansomes and worms where sequence sl RNA is spliced to the 5 ends of many precursor mRNAs
3. the capping processes takes place during:
5. is formed when the intron is cleaved at the 5 splice site and 5 end is joined to a 2 position at an A at the branch sit in the intron
7. cleaves target DNA to allow insertion of the introns at a new site
8. snRNAs found in the cyctoplasm
9. plays a role in xenopus embryonic development
11. together with some additional proteins, the snRNPs form the:
13. group of introns that excise themselves from RNA by an autocatalytic splicing event
15. are able to insert themselves into new sites
16. are the sequences that are removed in rna splicing
18. is a ribonucleoprotein in which the RNA has catalytic activity
21. infectious RNA molecules that function independently without encapsidation by any protein coat
