addition of 5’cap
addition of 3’ poly A tailremoval of introns
is a guanine nucleotide added backwards (5’ to 5’ bond) to the 5’ end of the mRNA (Fig 14.6)Functions: binding of ribosome to mRNA for translation, stabilizes mRNA, affects intron removal
50-250 adenine nucleotides at 3’ of mRNA.-Functions: Increases stability of mRNA; required for ribosome binding to 5’ cap
Is a large structure that the splicing occurs within; made of proteins and RNA (snRNA)
