All of the following statements are accurate except: snRNPs are an important component of the ribosome. Some snRNPs orchestrate splicing by complementary base pairing with conserved sequences in the pre-mRNA. Some snRNPs function as ribozymes, i.e. they catalyze chemical reactions in the splicing process. snRNPs are short nuclear RNAs complexed with splicing proteins. snRNPs are an important component of the spliceosome.
