  15. 3 regions required for proper intron removal 07_15_end_intron.jpg Just learn that there is an ‘AG’ on the 5’ side and an ‘A’ on the 3’ end as well as an ‘A’ in the intron itself…

  16. 07_16_RNA_chain .jpg • Performed by snRNA in association • With proteins = snRNP • Do not learn the whole slide…

  17. 07_17_spliceosome.jpg SPLICEOSOME - a complex of proteins and RNA which performs the actual splicing action. You will not be tested on this slide

  38. RNA makes copies of itself via first making a complementary RNA strand, which is itself used to make the copy RNA 07_39_copy_itself.jpg

  39. RNA can act as an enzyme!! Here it catalyses the cleavage of an RNA substrate 07_40_ribozyme.jpg
