Understand that RNA processing is a series of modifications that a primary RNA transcript undergoes to become a mature RNA molecule.
Recognize that in eukaryotes, RNA processing includes mechanisms such as splicing, 5' capping, and polyadenylation.
Identify that prokaryotes, unlike eukaryotes, do not have a nucleus, and their RNA does not undergo the same extensive processing.
Note that in prokaryotes, the primary RNA transcript is often translated into protein without the need for splicing, 5' capping, or polyadenylation.
Conclude that none of the listed RNA processing mechanisms (splicing, 5' capping, polyadenylation) occur in prokaryotes, as these are specific to eukaryotic cells.
